Abstract
A method and apparatus for measuring the frequency of a cyclically-repeating electrical signal by: passing the electrical signal through a network of sequentially-activated gates, in which the first gate detects the leading edge of each cycle of the electrical signal, and each of the remaining gates, when activated, applies a predetermine propagation delay to the detected leading edges; determining the gates which were activated at the beginning, and at the end, of a predetermined time window; determining the difference in the total propagation delays at the outputs of the activated gates; and utilizing the differences in the total propagation delays in determining the frequency of the electrical signal.
