<p>Apparatus (28) for applying a delay to an input signal (50) includes a plurality of delay devices (40), each having an input and an output, coupled in series such that the output of each of the delay devices, except for a final delay device (51) in the series, is coupled to the input of a succeeding one of the delay devices in the series. A switching unit (34) is adapted to receive a delay selection signal indicative of a desired time delay and, responsive thereto, to couple the input signal to the input of a designated one of the delay devices, so as to generate an output signal (100) at the output of the final delay device which is delayed with respect to the input signal by the desired time delay.</p> |
