ABSTRACT:
A pulse detector keeps track of the peak value of an analog input signal and clocks output data pulses into a flipflop and shift register at peak values thereof while it monotonically increases in magnitude for each polarity. The data input to the flipflop becomes logic zero once the analog input signal changes direction toward the opposite polarity, whereby the last output data pulse in the shift register corresponds to the maximum peak of the analog input signal during the given polarity.
