oscillator (physics)
Any device producing a desired oscillation (vibration). There are many types of oscillator for different purposes. These involve various arrangements of thermionic valves or components such as transistors, inductors, capacitors, and resistors.
An oscillator is an essential part of a radio transmitter, generating the high-frequency carrier signal necessary for radio communication. The frequency is often controlled by the vibrations set up in a crystal (such as quartz).
