1. A method comprising:

  • (a) receiving a periodic signal, the periodic signal having periodic signal cycles with corresponding time durations, wherein the time durations of the periodic signal cycles are substantially identical;

    (b) generating a control signal having a magnitude, the magnitude of the control signal varying smoothly over a plurality of the periodic signal cycles; and

    (c) delaying the periodic signal and thereby generating an output signal, wherein the output signal has output signal cycles with corresponding time durations, and wherein each of the time durations of the output signal cycles is a function of the magnitude of the control signal during the time duration.
