Comb generator

A comb generator, also known as a harmonic generator, is a device that creates a series of high-frequency signals, or harmonics, from a single input signal. It uses a specialized circuit called a "non-linear device" or "time-varying element" to split the input wave into multiple signals at multiples of its original frequency. This results in a spectrum of signals that look like the teeth of a comb, hence the name. Comb generators are used in applications like radio communications, signal processing, and testing to produce precise, high-frequency signals from a simpler source.
