Abstract : A high speed frequency acquisition apparatus utilizes a variable rate clocking circuit to establish the response time of the frequency comparator which compares the desired frequency with a reference frequency. The clocking circuit rate is determined by the inverse of the frequency difference between the two frequency signals.
