Oscillators -
(437 companies)
Oscillators are devices that are used to generate repetitive signals. They produce output signals without an input signal. There are two major types of electronic oscillators: harmonic oscillators and relaxation oscillators. Harmonic oscillators produce sine wave outputs. Relaxation oscillators produce non-sine wave outputs such as square wave, rectangular wave, and sawtooth outputs.

Monostable Multivibrators -
(21 companies)
Monostable multivibrators, also known as one-shots, are digital devices similar to flip-flops, but with only one stable state where they remain until triggered by an input signal. Once triggered, the output is switched to the opposite state.
