Af Drive Indicator Circuit
This circuit was utilized with an audio power amplifier to identify the point at which the output is -3 dB from maximum, indicated by LED D5, and at clipping, shown by LED D6. The indicator can be employed with any...
Audio Subcarrier Oscillator
A single integrated circuit (IC) provides all amplifiers: the 74HC04 Hex Inverter, which is a digital component. The second oscillator synchronizes to three times the frequency of the first oscillator, thereby tripling the frequency modulation (FM) deviation. Utilizing the lower...
Acousto-optic detector circuit to measure the crystal
The circuit consists of a capacitance three-point oscillator, an isolation level, a voltage doubler rectifier circuit, a stereo sound circuit, and a flash display circuit. It can detect the quality of a crystal; a good crystal will emit a "Didi"...
Improved 3 Transistor Audio Amp
Improved 3 Transistor Audio Amplifier. The load resistor for the driver transistor is connected directly to the positive supply. This configuration has a disadvantage in that as the output moves positive, the voltage drop across...

Zero Feedback Impedance Amplifiers
The amplifier in question is comparable to another model that has a lower parts count. It is worthy of construction.
The amplifier under discussion features a simplified design that maintains high performance while reducing the number of components required for assembly....
Two-function-signal-generator
This circuit allows for continuous variation of the frequencies of the triangle and square waves produced, covering a full decade. When the resistance of RS is approximately equal to R3, the amplitudes of the two waveforms will be equal (A_SQUARE...
Audio-generator
This circuit generates a sinusoidal output of approximately 8 V peak-to-peak, which can be adjusted down to zero, operating at a frequency of about 500 Hz. The signal is produced by a phase-shift oscillator.
The described circuit utilizes a phase-shift oscillator,...
Simple Audio Peak Detector
This audio peak detector enables the monitoring of a pair of stereo channels using a single LED. The circuitry employed for both the left and right channels is identical.
The audio peak detector circuit is designed to provide a visual indication...
Electronic Drum Synthesizer
The circuit consists of two twin-T oscillators set below the oscillation threshold. To initiate oscillation, a touch on the Touch Pad is required. The schematic diagram illustrates the circuit, where different touch patterns on the pads can create a variety...
