NTE783 Integrated Circuit Automatic Fine–Tuning Detector
Description: Specifically intended for use in the automatic fine tuning (AFT) system of color television receivers, the NTE783 AFT Detector provides all of the required circuitry except the tuning component. The device embodies a high–gain input amplifier and automatic gain control (AGC) circuitry to provide excellent sensitivity in TV AFT systems employing low level IF amplifiers.
