ASCO-29.4912MHZ-EK-T

Oscillators

An oscillator is an electronic circuit which produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices from clocks to radio transmitters and digital logic systems. The frequency of an oscillator is usually expressed in hertz (Hz).
