Abstract

1522005 Pulse discriminating ASEA AB 30 Oct 1975 [23 Dec 1974] 44930/75 Heading H3T Large amplitude pulses arriving directly from a source are distinguished from smaller amplitude reflected pulses by means of a signal variable threshold circuit. Peak detector A responds to the peaks of the largest pulses and attenuator 13 sets a threshold slightly less than this so that smaller amplitude pulses produce no output from comparator C.
