Ctfrmh

Margenau-Hill time-frequency distribution.

Calling Sequence

[TFR,T,F]=Ctfrmh(X)
[TFR,T,F]=Ctfrmh(X,T)
[TFR,T,F]=Ctfrmh(X,T,N)

Parameters

X :

Analyzed signal.

T :

time instant(s) (default : 1:length(X)).

N :

number of frequency bins (default : length(X)).

TFR :

time-frequency representation.

F :

vector of normalized frequencies.

Description

computes the Margenau-Hill distribution of a signal X.

Examples

x = hilbert(sin(2*%pi*0.25*(1:128))+0.5*rand(1,128,'normal'));
t=1:128; [tfr,T,F]=Ctfrmh(x,t,128);
grayplot(T,F,tfr');  xlabel('time'); ylabel('frequency')
