WebMar 5, 2005 · Any kind of filtered noise signal can be called 'colored noise', which is just to say that it is not a pure white noise. In audio, the most common color encountered is 'pink noise': Realized as sound, white noise sounds like the hiss of an untuned FM radio, or the background noise on a cassette tape player. Because of the particular ... WebMethod: (1) generate vector x(t) of white noise samples; (2) FFT it to produce X(f) (actually, this is unnecessary, since transformed white noise is white in frequency, too); (3) multiply by the filter H(f) to obtain Y(f); (4) inverse FFT to obtain y (t).
