ABSTRACT:
A device for filtering a signal delivered as output from a sensor installed in a motor vehicle includes a comparator (A) offering as output a first logic signal (SA) representative of the positive and negative transitions of the output signal (SM) from the sensor, a clock (G) delivering a signal (SG) serving as time base for the whole device, elements (E, D, F) making it possible to fix a filtering time (TFilt) of the output signal (SM) from the sensor, a suppression block (B) receiving as input the first logic signal (SA) and delivering as output a second logic signal (Sb) whose duration of holding (tn) in a logic state depends on the filtering time (TFilt), and a control block (C) managing the set of the signals of the device, and having as input signals the first and second logic signals (SA, Sb).
