Line 4: Assuming that a receiver is nearly tuned to the desired frequency, a [[electrical network\|circuit]] in the receiver develops an error [[voltage]] proportional to the degree to which the receiver is mistuned. This error voltage is then fed back to the tuning circuit in such a way that the tuning error is reduced. In most [[frequency modulation]] (FM) detectors an error voltage of this type is easily available. See [[Negative feedback]]. ~~The~~ AFC is also called Automatic Fine Tuning (AFT) in radio and TV receivers. It became rare in this application, late in the 20th century, as the more effective [[frequency synthesizer]] method became cheaper and more widespread. ==See also== *[[Frequency synthesizer]]
