AM To FM converter

This voltage-to-frequency converter is designed to connect to a frequency counter to display the measured voltage value. This converter-counter combination creates an inexpensive yet functionally complete digital voltmeter. The circuit outputs TTL-compatible pulses that are 5 µs wide. The...

This circuit is a simple 8-bit analog-to-digital converter (ADC) that connects to a PC serial port. It utilizes the TLC548 A/D converter chip, which is known for its serial output. However, the output from the TLC548 is not directly...

The work process analysis circuit diagram illustrates the use of a flyback converter transformer model. The flyback transformer primarily consists of ideal transformer magnetizing inductance and leakage inductance components. The flyback converter circuit exhibits high-frequency resonance at both ends...

The sub-harmonic bass generator is a sound-producing unit designed for guitars, capable of generating sounds similar to those of a bass guitar. This device employs an octave generator that operates differently from traditional sound coloring methods such as filtering...

This circuit accepts positive, negative, or differential control voltages. When the control voltage is zero, the output frequency is also zero. The described circuit functions as a versatile control voltage interface, capable of processing a range of input signals, including...

This is a low-cost accurate square-root circuit. This circuit is used to provide a square-root function with good accuracy. The benefit of this circuit is its affordability and precision. The low-cost accurate square-root circuit typically employs operational amplifiers (op-amps), resistors,...
