AmplifierCircuits

GENERAL DESCRIPTION: The TDA1001B is a monolithic integrated circuit for suppressing interference and noise in FM mono and stereo receivers. Features: • Active low-pass and high-pass filters • Interference pulse detector with adjustable and controllable response sensitivity • Noise detector designed for FM i.f. amplifiers with ratio detectors or quadrature detectors • Schmitt trigger for generating an interference suppression pulse • Active pilot tone generation (19 kHz) • Internal voltage stabilization Circuit Diagram: Interference and noise suppression circuit for FM receivers TDA1001B Datasheet for TDA1001B:   Download
