ABSTRACT:
A signal detection apparatus wherein pulses of the reverse polarity to that of the signal pulse to be detected are detected from an input pulse signal, and thereafter the signal outputting path is cut off for a fixed period, so that noise pulses which have oscillating waveforms in both positive and negative polarites are segregated from the signal pulses which can be provided with a unipolarity, by making use of the difference in polarity, and thereby, the noise pulses are eliminated regardless of their pulse heights. Further, the signal input to the cut-off circuit is delayed for a fixed period of time so that the first peak of the noise pulses may be eliminated even if it is of the same polarity as that of the signal pulse.
