ABSTRACT:
A method of operating a delay circuit to impose a selected delay on an electronic signal the delay circuit comprising a plurality of delay stages and means for directing the electronic signal through selected ones of the delay stages, the method comprising the steps of: measuring the actual signal delay through each of the delay stages; and selecting, based on the signal delays obtained in the measuring step, the delay stages through which the electronic signal is directed.
