ccepstrum (MathScript RT Module Function)
Owning Class: spectral analysis
Requires: MathScript RT Module
Syntax
c = ccepstrum(a)
c = ccepstrum(a, b)
[c, d] = ccepstrum(a)
[c, d] = ccepstrum(a, b)
Legacy Name: cceps
Description
Computes the complex cepstrum of a real signal.
Inputs
| 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. |
Outputs
| Name | Description |
|---|---|
| c | Returns the cepstrum of a. |
| d | Returns the number of padded elements (circular shifts). LabVIEW calculates d before c. |
Examples
X = 0:0.01:2;
Y = cos(100*X);
Z = 0.8*Y;
Z(1:25) = 0;
W = ccepstrum(Y+Z);
plot(X, W)
