Abstract
Abstract A PEAK DETECTOR DERIVES PEAK PULSES SEPARATED BY TIME INTERVALS SUBJECT TO VARIATION FROM A MODULATED BINARY DATA SIGNAL. BINARY DATA SIGNALS ARE DETECTED AND SEPARATED FROM THE MODULATED BINARY DATA SIGNAL. CLOCK SIGNALS ARE DETECTED AND SEPARATED FROM THE MODULATED BINARY DATA SIGNAL. A CONTROL OPERATED BY THE PEAK PULSES CONTROLS THE OPERATION OF EACH OF THE DATA AND CLOCK DERIVING CIRCUITS AND COMPRISES A TIME VARYING CIRCUIT FOR VARYING THE TIME POSITION OF THE CLOCK SIGNALS TO OVERCOME VARIATIONS IN THE TIME INTERVALS BETWEEN THE PEAK PULSES.
