<p>A stencil generator (500) for automatically constructing a stencil representative of signals having similar characteristics includes a boundary extractor (542) and a component generator (550). The boundary extractor (542) is operable to (i) receive a frequency spectrum of a signal, and (ii) obtain from the received frequency spectrum a plurality of characteristic frequency boundaries for the signal. The component generator (550) is coupled to the boundary extractor (542) and is operable to (i) receive the frequency spectrum, (ii) receive the plurality of characteristic frequency boundaries from the boundary extractor, and (iii) define a plurality of stencil components based upon the plurality of characteristic frequency boundaries and the frequency spectrum. In particular embodiment of the stencil generator (500), the boundary extractor (542) includes an integrator (544) and a linear regression comparator (548).</p> |
