What is a pulse generator circuit and its applications?
1 Answer
A pulse generator circuit is an electronic circuit designed to produce pulses of specific duration and frequency. It generates a series of square or rectangular waveforms with a defined high (ON) and low (OFF) period. Pulse generator circuits find applications in various fields, including electronics testing, signal conditioning, timing, and control systems. Here's a brief explanation of its working and applications:
Working of Pulse Generator Circuit:
A pulse generator circuit typically uses components such as resistors, capacitors, and transistors or integrated circuits to generate square wave pulses. The circuit's time constant determines the pulse width and frequency. By adjusting the values of these components, you can control the pulse characteristics, like pulse width, duty cycle, and frequency.
