Oscillators

Oscillators are electronic devices that operate based on the principles of oscillation, or repeating motion, in order to generate an output signal. Oscillators have a wide range of applications, including the generation of radio signals for communication, radar systems for detecting aircraft, and clock generators used in digital electronics. Oscillators are also used to create musical sounds and to generate signals to measure and control physical properties such as pressure, temperature, and position.
