Using this terminology, a 10Ah battery being charged at a C/5 rate corresponds to a 2.0A current. Exceeding this maximum rate should be done only with the manufacturer's permission. Some particularly robust batteries may be charged at a 1C rate (or even higher). However, this usually requires a charger that is custom designed for the battery. The size of an off-theshelf charger should generally be chosen so that the C/5 rate is not exceeded.

This type of splitter and combiner, which are the key elements of the amplifier, are called baluns (BALanced UNbalanced). They transform a balanced system that is symmetrical with respect to ground to an unbalanced system with one side grounded. Note that the push-pull RF amplifier is two independent devices each amplifying an individual signal of half the total power. Figure 1 shows the conceptual block diagram of a push-pull amplifier.

Unfortunately, as is the nature of the interweb, a few of the links have moved or gone dead. In fact, several now point to those crappy search sites, where some fool has gone in and made a page that looks like what you're looking for, but they are all paid links. So I went down the list and tracked down the bad links. Then I tried to find the new home of those plugins. What follows is the list of apps linked from the page, with what I found for each one.

The spectrum compromises the 50 Hz to 15 kHz stereo channel plus an additional stereo channel frequency division multiplexed into a composite baseband signal with a 19 kHz pilot. The three channels are (1) the left (L) plus the right (R) audio channels, (2) the left plus the inverted right audio channels, and (3) the SCA subcarrier and its associated sidebands.Figure 1.

Antenna improvements affect both the transmitted and received signal and thus increase your operating range. Once you reach a certain point, the only practical way to get bigger antennas is to put up multiple antennas phased in such a way so that the total gain of the array increases (hopefully). For VHF and above this usually requires the ubiquitous power divider. Over the years I have built power dividers using coaxial cable or round copper tubing to achieve the necessary matching of the various antennas in an array. Recently, I have been using waveguide to construct 2 and 4 way power dividers. The waveguide has the advantage of being rectangular which greatly facilitates the attachment of the coaxial cable connectors. It is also made of copper, unlike power dividers made of square or rectangular aluminum tubing, which means the whole assembly can be soldered for long lasting, waterproof, electrical connections.

The quiescent current with 1A of output current and an input-output differential of 5V is therefore only 30 mA. Designed also for vehicular applications, the LM2940/LM2940C and all regulated circuitry are protected from reverse battery installations or 2-battery jumps. During line transients, such as load dump when the input voltage can momentarily exceed the specified maximum operating voltage, the regulator will automatically shut down to protect both the internal circuits and the load. The LM2940/LM2940C cannot be harmed by temporary mirror-image insertion. Familiar regulator features such as short circuit and thermal overload protection are also provided.

The use of a PNP power transistor provides a low dropout voltage characteristic. With a load current of 500 mA the minimum input to output voltage differential required for the output to remain in regulation is typically 0.5V (1V guaranteed maximum over the full operating temperature range). Special circuitry has been incorporated to minimize the quiescent current to typically only 10 mA with a full 500 mA load current when the input to output voltage differential is greater than 3V. The LM2937 requires an output bypass capacitor for stability. As with most low dropout regulators, the ESR of this capacitor remains a critical design parameter, but the LM2937 includes special compensation circuitry that relaxes ESR requirements. The LM2937 is stable for all ESR below 3Ω. This allows the use of low ESR chip capacitors. Ideally suited for automotive applications, the LM2937 will protect itself and any load circuitry from reverse battery connections, two-battery jumps and up to +60V/-50V load dump transients. Familiar regulator features such as short circuit and thermal shutdown protection are also built in.

The microprocessor reset flag is set low by thermal shutdown, short circuits, overvoltage conditions, dropout, and power-up. After the fault condition is corrected, the reset flag remains low for a delay time determined by the delay capacitor. Hysteresis is included in the reset circuit to prevent oscillations, and a reset output is guaranteed down to 3.2V supply input.

The LA1832 provides an FM IF, FM multiplex detection, AM tuning, and the AM IF functions. The MC13028A provides the AM Stereo detection as well as Left and Right audio outputs. An MC145151 synthesizer provides the frequency control of the local oscillator contained within the LA1832. Frequency selection is by means of a switch array attached to the synthesizer.The MC13028A is designed as a low voltage, low cost decoder for the C–QUAM AM Stereo technology and is completely compatible with existing monaural AM transmissions. The IC requires relatively few, inexpensive external parts to produce a full featured C–QUAM AM Stereo implementation. The layout is straightforward and should produce excellent stereo performance. This device performs the function of IF amplification, AGC, modulation detection, pilot tone detection, signal quality inspection, and left and right audio output matrix operation. The IC is targeted for use in portable and home AM Stereo radio applications.

The MC13025 provides a high dynamic range mixer, voltage controlled oscillator, and first IF that with the MC13022 and synthesizer form a complete digitally controlled AM stereo tuner system. This system in turn may drive a dual channel audio processor and high power amplifiers for car radio or home stereo applications. Other applications include portable radio “boom boxes”, table radios and component stereo systems. Functionally, the MC13022A and MC13022 are very similar. The MC13022A has 10 dB more audio output and a CMOS compatible logic level output (Pin 15) for stop sense. The stop sense/AGC function has been internally connected to the output notch filter control.

The mode of operation is selected with the Mode pin (Pin 4) and appropriate power supplies (see Table 1). Each of the four outputs is capable of sourcing and sinking 60 to 70 mA while providing sufficient voltage to ensure proper data transmission. As differential drivers, data rates to 10 Mbaud can be transmitted over a twisted pair for a distance determined by the cable characteristics. EIA–422–A Standard provides guidelines for cable length versus data rate. The advantage of a differential (balanced) system over a single–ended system is greater noise immunity, common mode rejection, and higher data rates. Where extraneous noise sources are not a problem, the AM26LS30 may be configured as four single–ended drivers transmitting data rates to 100 Kbaud. Crosstalk among wires within a cable is controlled by the use of the slew rate control pins on the AM26LS30.

The circuit is ideal for detecting the presence, absence, or level of water, or other polar liquids. An AC signal is passed through two probes within the fluid. A detector determines the presence or absence of the fluid by comparing the resistance of the fluid between the probes with the resistance internal to the integrated circuit. An AC signal is used to overcome plating problems incurred by using a DC source. A pin is available for connecting an external resistance in cases where the fluid impedance is of a different magnitude than that of the internal resistor. When the probe resistance increases above the preset value, the oscillator signal is coupled to the base of the open-collector output transistor. In a typical application, the output could be used to drive a LED, loud speaker or a low current relay.

This will protect the loudspeaker in a bridge mode, when a DC short of the output occurs on one side of the speaker. The device will prevent the speaker from destruction by reducing the DC across the load (bridge mode) to typically less than 2 VDC(VS=14.4V,RL=4Ω), by an internal current pullback method.The LM2005 is a dual high power amplifier and pin for pin compatible with TDA2005, designed to deliver optimum performance and reliability for automotive applications. High current capability (3.5A) enables the device to deliver 10W/channel into 2Ω (LM2005T-S), or 20W bridged monaural (LM2005T-M) into 4Ω, with low distortion.

Overcharging can result in a reduction of battery life as well as physical harm to the end user. Since most portable applications require the batteries to be charged rapidly, a primary and usually a secondary or redundant charge sensing technique is employed into the charging system. It is also desirable to disable rapid charging if the battery voltage or temperature is either too high or too low. In order to address these issues, an economical and flexible fast charge controller was developed. The MC33340 and MC33342 contains many of the building blocks and protection features that are employed in modern high performance battery charger controllers that are specifically designed for Nickel Cadmium and Nickel Metal Hydride batteries. The device is designed to interface with either primary or secondary side regulators for easy implementation of a complete charging system.

It is a very small antenna, but very effective. It is vertically polarized. and has an omni-directional radiation pattern.The antenna's two principle elements are a flat conducting disc mounted horizontally atop, but insulated from, a conducting cone. The disc diameter is about 0.17 wavelength at the lowest desired operational frequency and the cone has a length of 0.25 wavelength on the side. The discone's impedance is 50 ohms, so it can be fed by a 50-ohm coaxial cable. The outer (shield) conductor is connected to the cone, the center conductor is connected to the disc. The antenna's actual impedance varies depending on the cone's angle, frequency, and disc-to-cone spacing. Nevertheless, discone dimensions are not very critical for optimum performance.

The choice involves considerations such as voltage, current, switching speed, drive circuitry, load, and temperature effects. There are a variety of solid state switch technologies available to perform switching functions; however, all have strong and weak points.By combining the low conduction loss of a BJT with the switching speed of a power MOSFET an optimal solid state switch would exist. The Insulated–Gate Bipolar Transistor (IGBT) technology offers a combination of these attributes.

Today, product design engineers often do not find themselves designing oscillators because the oscillator circuitry is provided on the device. However, the circuitry is not complete. Selection of the crystal and external capacitors have been left to the product design engineer. If the incorrect crystal and external capacitors are selected, it can lead to a product that does not operate properly, fails prematurely, or will not operate over the intended temperature range. For product success it is important that the designer understand how an oscillator operates in order to select the correct crystal.

Although there are fewer cars on the road, most fatal car accidents happen at night than any other time of the day. Our ability to see the road ahead is seriously impaired at night. Darkness can dramatically alter the driver's ability to cope with even the most normal driving conditions. As we are more vulnerable to dangerous road situations at night or in low visibility, we should double our preparedness, alertness and common sense when driving at night. Preventive maintenance is one of the best ways to protect ourselves from potentially dangerous situations on the road. Here are some of the most important points to consider when driving in the dark.

Do you feel that slight shimmy in the front end? Is there a new knocking sound under the hood? Is there a rattle in the dashboard? No one knows your car better than you do. If you feel something different, or if it isn't handling correctly take it to your mechanic. It could be something as simple as a tire out of alignment, or perhaps a loose belt. It's always best to find any small problem before it becomes a large one.

The first claimed audio transmission that could be termed a broadcast occurred on Christmas Eve in 1906, and was made by Reginald Fessenden. While many early experimenters attempted to create systems similar to radiotelephone devices where only two parties were meant to communicate, there were others who intended to transmit to larger audiences. Charles Herrold started broadcasting in California in 1909 and was carrying audio by the next year.

The comparators have two common signal inputs, PCAin and PCBin. Input PCAin can be used directly coupled to large voltage signals, or indirectly coupled (with a series capacitor) to small voltage signals. The self–bias circuit adjusts small voltage signals in the linear region of the amplifier. Phase comparator 1 (an exclusive OR gate) provides a digital error signal PC1out, and maintains 90° phase shift at the center frequency between PCAin and PCBin signals (both at 50% duty cycle). Phase comparator 2 (with leading edge sensing logic) provides digital error signals, PC2out and LD, and maintains a 0° phase shift between PCAin and PCBin signals (duty cycle is immaterial). The linear VCO produces an output signal VCOout whose frequency is determined by the voltage of input VCOin and the capacitor and resistors connected to pins C1A, C1B, R1, and R2. The source–follower output SFout with an external resistor is used where the VCOin signal is needed but no loading can be tolerated. The inhibit input Inh, when high, disables the VCO and source follower to minimize standby power consumption. The zener diode can be used to assist in power supply regulation.

The antenna is basically a quad opened up on the bottom. This up and over, over and down design had been used in HF wire antennas. The antenna acts like a stacked pair on the vertical and a standard yagi on horizontal. The prototype for 2 meters made its first contact of over 200 miles while lying upside down on a picnic table. This lead to the discovery that it can be used very low to the gound by inverting it. This method can also be used when there is match problems due to nearby objects. A 440 version with suction cups allowed an apartment dweller to have a beam antenna stuck to his ceiling. The antenna is very forgiving of dimensions. The prototype had screws in the end of the elements for adjusting but at 2 meters, 1/4 inch changes did not affect performance. I highly recommend this for new builders. The only problem is that it fires off to the corner opposite the feed. Over the years I have seen the design renamed and modified by others, and posted on other web sites. This is the original.

The magnetic load is the secondary winding (or windings). The flux through the core links the windings to each other. It also enables electrical isolation between windings, and enables adaptation to different voltage levels by adjusting the turns ratio. Energy storage in a transformer core is an undesired parasitic element. With a high permeability core material, energy storage is minimal.

The new power supply is also a forward converter with a half-bridge topology. The difference to the modified PC power supply consists in the following items: Two power FETs instead of bipolar transistors used as power switches, a synchronous rectifier on the secondary side instead of power diodes, the lack of a driver stage (current-proportional control) and a more simple over-current and over-voltage monitor. With the magnetic components (output transformer, driver transformer, chokes...) stripped from a PC power supply, the new power supply delivers a max. power output of 250 W, whereby the efficiency amounts up to 90 %. The power supply can handle 20 % over-load for a short duration.

It has evolved from the original gold-doped saturated 7400 logic, to Schottky-Clamped logic, and finally to the modern advanced families of TTL logic. The popularity of these TTL families stem from their ease of use, low cost, medium-to-high speed operation, and good output drive capability.

The stereo coder is a simple application that runs with Windows XP with service pack 1 or higher.Airomate makes it possible to use a 192 kHz sampling rate capable soundcard to generate a high quality stereo MPX signal with full featured RDS/RBDS for FM radio transmitters. Airomate gives your radio station the professional look and sound.The maximum frequency of a MPX stereo / RDS signal goes up to 57 kHz. So you need a soundcard that can handle a minimum frequency of 57 kHz. Nowadays there are cheap soundcards which have a samplerate of 192 kHz. These soundcards can produce frequencies up to 96 kHz. For a frequency of 96 kHz you will need a minimum samplerate of 192 kHz. Most operating systems can not handle a samplerate of 192 kHz. Windows XP WITH Service pack 1 is the first Windows version which can handle this.

The basic J-Pole has a gain comparable to a dipole - about 2.5DBi. The author wanted something better, so he investigated several types of antennas. An omnidirectional pattern was desired. Also, minimal skyward radiation and minimal radiation back to the building on which the antenna is installed was a requirement. A vertical design addressed these concerns. The radiation pattern of this antenna approximates that of a doughnut lying on its side. Maximal coverage of populated areas is achieved in this way. The gain of the antenna described herein is about 8.8DBi. Switching to this antenna has much the same effect as tripling or quadrupling transmitter power.

The following circularly-polarized design is based on the Harris Dual Cycloid III, a C.P. antenna for FM up to 1KW. This antenna is not recommended for transmitters below 10 watts. However, because of its circularly-polarized pattern, this antenna will often outperform vertical antennas over hills and valleys. The gain with two bays is just about break-even, so more transmitter power is necessary to maintain the same intensity in your coverage area's strong spots. In my experience, this antenna produced a receivable signal in many isolated areas that were completely dead with a vertical J-pole that was in use before. The history of C.P. and some documentation I have on the subject indicates that doubling transmitter power is all that's necessary when switching to this polarization type. If you have adequate power to service your primary area, you'll find that your dead zones are greatly reduced or almost eliminated.

Switch Mode Power Supplies are the current state of the art in high efficiency power supplies. Conventional series-regulated linear power supplies maintain a constant voltage by varying their resistance to cope with input voltage changes or load current demand changes. The linear regulator can, therefore, tend to be very inefficient. The switch mode power supply, however, uses a high frequency switch (in practice a transistor) with varying duty cycle to maintain the output voltage. The output voltage variations caused by the switching are filtered out by an LC filter.

The FCC authorized stereophonic transmission for the commercial FM broadcast band. With stereophonic transmission, the information signal is spatially divided into two 50-Hz to 15-kHz audio channels (a left and a right). Music that originated on the left side is reproduced only on the left speaker, and music that originated on the right side is reproduced only on the right speaker. The main problem with introducing stereophonic transmission is the compatibility with monophonic receivers.

This stemmed directly from some of FM's properties : Better rejection than AM of spurious signals from your girlfriend's Hair Dryer Electrical sparks, Lightning etc are normally AM sources, rejected by FM receivers More distance on the dial between FM stations FM Stations are 200 KHz away from each other. FM Bandwidth = 2 ( deviation + input signal frequency). As FM is designed to handle Audio from 20Hz to 15 KHz, this gives lots of room to put in the Audio spectrum twice over + even more information in one channel without infringing on the other channel. AM stations on the other hand are spaced 9 or 10 KHz away from each other.

Thus the information is held in the zero crossings. The FM waveform can be clipped at a low level without the loss of information. Additive noise has less of an effect on zero crossings than the amplitude. Receivers therefore often clip, or limit the amplitude of the received waveform prior to frequency detection.

This gain is measured in decibels-isotropic ( dBi ) or in decibel-dipole ( dBd ). The decibel is a unit of comparison to a reference. The letter following the dB indicates the reference used. The dBi is a unit measuring how much better the antenna is compared to an isotropic radiator.
