ABSTRACT:
An open loop digital frequency multiplier with a multiplied output synchonized to low frequency clock pulses. The system includes a multi-stage digital counter which provides a pulse output as a function of an integer divisor. The integer divisor and the timing or counting cycle of the counter are interrelated to the frequency of a clock input. The counting cycle is controlled by a one-shot multivibrator which, in turn, is driven by a reference frequency input.
