This is a 1 watt fm amplifier with a good design that can be used to amplify a rf signal in the 88 108 MHz band. It is very sensitive if you use good rf power amplifier transistors, trimmers and coils. It has a power amplification factor of 9 to 12 dB (9 to....

A charge amplifier is an amplifier whose equivalent input impedance is a capacitive reactance that is very high at low frequencies. Thus contrary to what its name may suggest, a charge amplifier does not amplify the electric charge present at its input. Its....

The circuit is placed parallel with the exit of power amplifier and us gives the level of signal ,from output. Changing resistance R1, in the input circuit, we adapt the indication of power, in the resistance of loudspeaker, that we use....

The crossover network is intended for use when an existing audio installation is to be extended by the addition of a subwoofer. Often, this additional loudspeaker is one that has been lying around for some time. If its frequency response extends down far....

This project involves constructing an energy efficient broad spectrum LED lamp system. The lamp is useful for indoor reflective room lighting. It has a broad color spectrum that more closely approximates the light of the sun when compared to fluorescent....

An electromagnetic field probe designed to detect changing electric and magnetic fields. The probe has switchable gain, a frequency response up to 400kHz and independent audio and meter monitoring. This EMF probe uses an inductor to locate stray....

The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. An additional control input allows loudness compensation to be simply effected. Four control inputs provide control of....

The TDA7294 amplifier module is a monolithic integrated circuit. It is intended for use as an audio class AB amplifier in hi-fi applications. It has a wide voltage range and output current capability, enabling it to supply the highest power into both 4 ohm....

Can a 555 negative supply circuit, like the one below I pulled from another schematic, supply enough negative voltage to a LM324 and a AD736JN? I`m....

This simple circuit was a presented, it can give power output about 1 watt, when connected to a power supply 9 volt. The advantage of this circuit is that it uses a dual darling ton to increase the size as much as of input impedance about 20 Meg ohm. This....

The RF amplifier uses noiseless feedback through the drain-gate capacitance with an inductor in the source lead to provide the necessary 90 degree phase shift between gate voltage and channel current...

If you are looking for a micro mixer circuit that create a simple, affordable, small and compact, and be usable versatile, must be this circuit. We can use to mix up to four input channels such as the microphone signal, FM Tuner, AUX and Other signals, As....

The TA1284FN is TV Tuner IC which integrate mixer / Oscillator for VHF and CATV bands, mixer / Oscillator for UHF band, and IF Amplifier on a single chip. Supply voltage of 5 V helps lower power dissipation from the set. Compact 16-pin SSOP makes the Tuner....

2 x 18W Hi-Fi Stereo Power Amplifier based around two TDA2030 ICs. It has good input sensitivity, low distortion, good operating stability and full protection against overloads and output short-circuits. It can be used as a booster amplifier for existing....

Explore power amplifier integrated circuit from National Semiconductor LM4780. What`s so special Well, first of all - a very low harmonic distortion. In general, manufacturers indicate the maximum power of his ingenious craft regularly with the harmonic....

This is a senior project from Stony Brook University, which is designed and implemented by Tak-Fung Yip, Franklin Delgado, and consulted by professor Milutin Stanac....

The circuit was designed according to the RIAA implementation of Hi-Fi phono preamplifier for the purpose of reproducing an audio from a moving magnet car....

As you can see, in this architecture the apparatus accept a big tolerance, so you can body it about of the components, which you acquisition at home. The and transistors can be any NPN blazon ability transistor, but do not use Darlington types The....

Here`s the circuit diagram based on PIR motion sensor module BS1600 (or BS1700) that can be used for security lighting in power saving mode. (If you could not found one in your local store, buy PIR motion sensor online). The special advantage of this motion....

We published a design for a stereo microphone preamplifier with balanced inputs and a phantom power supply. The heart of this circuit was a special Analog....

This circuit generates a two-tone effect very much alike the cuckoo song. It can be used for door-bells or other purposes thanks to a built-in audio amplifier and loudspeaker. Used as a sound effect generator it can be connected to external amplifiers, tape....
