In [[radio]] equipment, '''Automatic Frequency Control''' (AFC) is a method (or device) to automatically keep a [[resonant circuit]] [[Tuner (electronics)|tuned]] to the [[frequency]] of an incoming [[radio signal]]. It is primarily used in [[radio receiver]]s to keep the receiver [[Tuner (electronics)|tuned]] to the frequency of the desired station.
