SOME ELECTROMECHANICAL METHODS FOR PRODUCING LOW FREQUENCIES FROM A PRIMARY FREQUENCY STANDARD

Abstract

Minor mechanical modifications to the clock motor of a quartz crystal primary standard of frequency simplify the problem of producing accurate low frequencies. Electromechanical gate circuits are used to provide pulses of high stability at repetition rates of 1, 10, 100, and 1000 pulses per second for stroboscopic and other applications.
