What is a Relaxation Oscilloscope?

Relaxation Oscillator Definition

A relaxation oscillator is defined as a non-linear electronic circuit that generates non-sinusoidal repetitive signals, such as square and triangular waves.

Components and Function

It utilizes non-linear elements and energy-storing components like capacitors and inductors, which charge and discharge to create oscillations.

Working Principle

The operation is based on the continuous charging and discharging of an energy-storing component, determining the waveform and frequency of the output.

Circuit Varieties

Op-Amp relaxation oscillators

UJT relaxation oscillators
