Circuit de traitement de signaux pour detecteur de mouvements

Signal processing circuit for a moving detection circuit

Abstract

ABSTRACT OF THE DISCLOSURE A signal processing circuit for a moving detection circuit which has a coefficient generator which is connected to an output of a moving detection circuit. A level comparator is connected between the moving detection circuit and the coefficient generator and is also connected to a threshold voltage switch. An isolated-point eliminating circuit is connected between the level comparator and a time base filter which is connected at its output terminal to the input terminal of the coefficient generator. The coefficient generator includes a plurality of one bit delay devices which are connected in series and the plurality of one bit delay devices have a plurality of output terminals, and an adder is connected to the plurality of output terminals so as to add the output signals.
