ABSTRACT:
A circuit for the filtering of a pulse signal comprises means to detect an output pulse upon the detection of an input pulse, the shape of this output pulse being based on elementary delays obtained by the charging and discharging of capacitors. During the generation of the output pulse, no new input pulse can be taken into account.
