Noise induced hunting is eliminated in successive ranged digitalanalog converter bias correction circuits by means of a digital hysteresis circuit. The digital hysteresis circuit comprehends a first updown counter that counts to its extremums from a pre-set intermediate state in response to enable and updown input signals. For each extremum count an enable output pulse and a reset pulse is generated at the counter output. The enable output pulses are counted by a second updown counter the output of which drives a digitalanalog converter. Each reset pulse resets the first updown counter to its pre-set state. Author
