zak

Zak transform

Calling Sequence

DZT = zak(SIG,N,M)

Parameters

SIG :

Signal to be analysed (length(X)=N1).

N :

number of Zak coefficients in time (N1 must be a multiple of N) (default : closest integer towards sqrt(N1)).

M :

number of Zak coefficients in frequency (N1 must be a multiple of M) (default : M=N1/N).

DZT :

Output matrix (N,M) containing the discrete Zak transform.

Description

zak computes the Zak transform of signal SIG.

Examples

sig = fmlin(256);
DZT = zak(sig);
grayplot(1:16,1:16,DZT');
