rceps

Real cepstrum.

Calling Sequence

Xh=rceps(X)
[Xh,Yh]=rceps(X)

Parameters

X

Real input sequence.

Xh

Real cepstrum of the real input sequence.

Yh

Minimum phase reconstructed version of the real input sequence.

Description

Computes the cepstrum of a real sequence. The function also provides an option as second output argument for getting the reconstructed signal approximating the input sequence from the real cepstrum. This function is a clone of MATLAB's rceps function and hence gives similar results.

Examples

// real input sequence
X = [ 1  -1  3  -1  1  0  1  0];

// real cepstrum of x
Xh = rceps(X);

//if the reconstructed signal (yh) from cepstrum approximating x is desired 
[Xh, Yh] = rceps(X);
