1. A receiver for processing an input signal having a carrier frequency, the input signal having phase information, the receiver comprising:

  • (a) a first clock generator adapted to generate a first clock independent of the carrier frequency of the input signal, wherein the first clock has a first clock frequency;

    (b) a second clock generator adapted to generate a second clock independent of the carrier frequency of the input signal, wherein the second clock has a second clock frequency different from the first clock frequency;

    (c) a sampler adapted to sample the input signal exclusively using a selected sampling clock having a selected sampling frequency; and

    (d) a switch adapted to select one of the first and second clocks as the selected sampling clock for the input signal, wherein the selection of the selected sampling clock is dependent upon the carrier frequency of the input signal, wherein the clock frequency of the selected sampling clock is not harmonically related to the carrier frequency of the input signal.
