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
