Oscillators

An oscillator is a device which generates a continuous periodic signal, often regarded as a repeating waveform called a wave. These waveforms are generated through electrical or mechanical means, including chemical reactions, phase transitions, electromagnetic radiation, optical systems, and mechanical systems. Typically, oscillators are used to create and control the timing and spatial characteristics of certain electrical signals. Oscillators can be used in a variety of different applications, from communications and data recovery systems to biological and chemical experiments.
