摘要: A method for determining the period of a periodic signal, possibly including noise, includes step calculating signal representing difference between and delayed by time T. The variance representative is then computed. steps computing repeated different times determined to be T producing minimum variance. Apparatus implementing this source signal. circuit computes T, control varies selector selects as
