rceps() - Signal Processing
The real cepstrum is the inverse Fourier
transform of the real logarithm of the magnitude of the Fourier transform
of a sequence.Note
rceps only works on real data.rceps(x) returns the real cepstrum
of the real sequence x. The real cepstrum is a
real-valued function.[y,ym] = rceps(x) returns
both the real cepstrum y and a minimum phase reconstructed
version ym of the input sequence.
Syntax
rceps(x)[y,ym] = rceps(x)
Example
y = real(ifft(log(abs(fft(x)))));
