1. A programmable device comprising programmable circuitry:

  • operable in a first mode to receive a first signal having a frequency spectrum associated therewith, the frequency spectrum including a plurality of channels, and to determine a first noise level for each of the plurality of channels; and

    operable in a second mode to filter the first signal, thereby generating a plurality of filtered signals each filtered signal corresponding to one of the plurality of channels, and to monitor a second noise level associated with each of the filtered signals;

    wherein the channels associated with the filtered signals are selected for monitoring in the second mode based on the first noise levels determined in the first mode.
