automatic frequency control

He was also responsible for innovations in the design of automatic frequency control circuits, digital delay lines and condenser microphones.

The circuit was envisioned for automatic frequency control of receivers, but also found application in demodulating an FM signal.

Automatic frequency control (AFC) solves some of the drift problem, but manual retuning was often necessary.

This effect is used to good advantage for automatic frequency control in receivers, and in frequency modulation for transmitters.

They also installed a new 1000 watt transmitter with automatic frequency control and new speech amplifiers at their plant in Coytesville NJ.

Like the P-12 the radar features automatic frequency control with four pre-set operating frequencies, moving target indicator to eliminate passive clutter and active jamming, the radar could also display tracks from another radar it was paired with.
