Abstract
A digital hysteresis circuit which generates a stable signal for driving a digital readout indicator from an analog signal indicative of the position of a mechanical driving device having noise signal components leading to erratic indications superposed thereon. A reference signal generated by an up-down counter is compared with the digitized input signal in a memory store. Only when the difference in the compared digital values exceeds a predetermined digital hysteresis value in the memory store corresponding to the allowable noise signals is a command signal generated to increment or decrement the counter so as to reduce the difference in digital value. The reference signal is applied to drive the digital readout indicator, thereby precluding unstable indications due to noise, jitter, and system threshold uncertainty.
