Introduction to Oscillators

An oscillator is a circuit that creates a waveform on its own. It provides a method to generate a repeating waveform over a wide range of frequencies, under the control of an external device or process. The waveform can be fixed or variable, and is usually derived from some monotonic source such as a voltage generator. Oscillators are used in a diverse range of applications, ranging from communication systems and computers, to audio and video equipment, to medical and scientific instruments.
