1. A method of detecting a signal (S) of interest contained within a waveform (F) comprised of a plurality of frequencies within a frequency spectrum, as well as random noise, comprising:

  • capturing the waveform;

    converting the waveform from analog to digital;

    processing the digitized waveform; and

    , supplying results of the processing as an input to an oscillator (24) operating at a nominal output frequency, the oscillator canceling the effects of the noise in the waveform and shifting its output frequency to a different frequency which is a function of the signal of interest.
