ABSTRACT:
A digital pulse detection apparatus for correcting a distorted serial digital signal by differencing the signal and a delayed version of the signal in a differential amplifier to obtain the slope of the digital signal. The output signal from the differential amplifier is applied to a voltage hysteresis differential amplifier which provides the corrected digital output signal.
