With control set for maximum resistance, only desired a-c voltage peaks above 4.5 V are passed by diodes. Balanced variable-thresh-old circuit achieves this suppression of weak background noise without affecting a-c balance of signals.-W. E. Earle, A-C Threshold Converts to Switch, Electronics, 31;1, p 96-99.
