Calling Sequence

ComplexCepstrum(A)

Parameters

A

-

Array of real numeric values; the signal

Description

• 

The ComplexCepstrum(A) command uses the Fourier transform to compute the complex cepstrum of a signal and the number of samples of delay.

• 

A must be an one-dimensional Array and must contain real numbers only.
