ABSTRACT:
There is disclosed a threshold circuit for a long coded pulse having a given amplitude subdivided into a plurality of chips, each providing a code bit. A first circuit receives the coded pulse to compress the coded pulse into a shorter pulse of much greater amplitude than the given amplitude and to detect the compressed pulse. A second circuit also receives the coded pulse, detects the coded pulse and provides an amplitude threshold voltage. A third circuit coupled to the first and second circuits produces a finite output when the amplitude of the compressed pulse is greater than the amplitude of the threshold voltage and a zero output when the amplitude of the compressed pulse is less than the amplitude of the threshold voltage.
