Syntax

c = cceps(a)

c = cceps(a, b)

[c, d] = cceps(a)

[c, d] = cceps(a, b)

Computes the complex cepstrum of a real signal.

Name	Description
a	Specifies a real signal.
b	Controls the zero-padding of the signal specified by a. b is an integer and typically is a power of 2.

Name	Description
c	Returns the cepstrum of a.
d	Returns the number of padded elements (circular shifts). LabVIEW calculates d before c.

X = 0:0.01:2;
Y = cos(100*X);
Z = 0.8*Y;
Z(1:25) = 0;
W = cceps(Y+Z);
