Figure 9

Left: A (part of a) power spectrum of externally sequentially played tones (d, a) (overlapped in the FFT epoch), prominent line corresponding to the tone a; in the middle: the same spectrum combed with the fuzzy comb for c1; right: the same spectrum combed with the fuzzy comb for minor a. This illustrates the response of combing with the wrong and proper matching comb-like filter.
