Abstract
A method is provided for identifying the frequency of a logic signal that may have a frequency equal to one of n discrete frequencies. The method includes the steps of sequentially transmitting trains of clock pulses of decreasing frequencies. Each clock frequency is a constant multiple of one of the discrete frequencies. The time duration of the first train of clock pulses corresponds to the measurement time duration of a logic signal at the first discrete frequency. The time duration of the i.sup.th train of pulses is such that the sum of the time durations of the first to the i.sup.th pulse trains corresponds to the measurement time duration of a logic signal at the i.sup.th discrete frequency.
