Device for forming the pulses of a two-channel sensor responsive to the speed of displacement of an object to be monitored

摘要

The invention relates to measuring devices. The device forming the subject of the invention is characterised in that the former 8 of pulses of forward displacement of the object to be monitored comprises a circuit for filtering false signals during the said forward displacement, this filtering circuit consisting of four flip-flops 16 to 19 connected via their homologous inputs to the corresponding outputs of the pulse former 8 during the said forward displacement, the other input of each of the said flip-flops being connected to the said homologous input of each following flip-flop in such a way that the said other input of the last flip-flop is connected to the said homologous input of the first flip-flop and that one of the outputs of each of the flip-flops is connected to the corresponding input of the output pulse former 15. The invention applies in particular to the measurement of the angular speeds of wheels in anti-lock automobile brakes. <IMAGE>
