ABSTRACT:
The relative frequency of two signals is indicated by applying pulses indicative of the two signals to respective bistable flip-flops. The flip-flops are interconnected to produce two binary outputs each of which varies between two binary values in response to occurrence of the pulses. These binary outputs are applied to a logic circuit which produces a binary output that varies between two binary values as a function of the similarity and difference in binary values of the two flip-flop signals. The binary output of the logic circuit is applied to two further bistable flip-flops along with the pulses to control the outputs of the further flip-flops. The outputs of the further flip-flops produce respective signals which indicate the relative frequency of the two signals, and which can be used to change this relative frequency.
