ABSTRACT:
A continuous, momently constant amplitude signal is received through a lossy transmission medium and adapted to produce a distinct step-like series of pulse repetition rates therefrom which are proportional to the received signal amplitude. The relatively constant received signal is modulated into a sequence of distinctly separate amplitude steps which are level detected and adapted to produce a cyclic pulse rate proportional to the average value of the received signal. The cyclic pulse rate is employed directly to give aural or visual indication. Alternatively the cyclic pulse rate is adapted to provide a binary format signal for cooperation with a computer data bus or the like.
