Abstract: A novel pulse detection circuit for recognizing undesirable noise pulses within digital logic circuitry is disclosed. The detection circuit allows for pulse amplitude and pulse width discrimination and will generate output signals indicative of the presence of pulses of amplitude greater than a selected amplitude and width less than a selected duration. Logic voltage comparators and a variable reference voltage source are used to allow for variable pulse amplitude discrimination of both positive transition and negative transition incoming signals. An incoming signal of greater amplitude than a reference signal will be reflected in both a direct output pulse signal and an inverted output pulse signal of the voltage comparators. The direct output pulse signal is applied to a first flip-flop after being delayed by a first given interval of time.
