Abstract
A continuous counting system includes a multistage binary counter for deriving the frequency of an input signal by counting the cycles thereof occurring during predetermined timing intervals. A control circuit, responsive to the input signal and to a timing reference signal, develops an output pulse during each period of the timing reference signal extending between a logical transition of predetermined polarity of the reference signal and the subsequently occurring nth logical transition of like polarity of the input signal. The output pulses are coupled for presetting the binary counter to the count n whereby counts beginning with n+1 are accumulated during the remainder of the timing interval.
