tfrmh

Margenau-Hill time-frequency distribution.

Calling Sequence

[TFR,T,F]=tfrmh(X)
[TFR,T,F]=tfrmh(X,T)
[TFR,T,F]=tfrmh(X,T,N)
[TFR,T,F]=tfrmh(X,T,N,TRACE)
[TFR,T,F]=tfrmh(...,'plot')

Parameters

X :

signal if auto-MH, or [X1,X2] if cross-MH.

T :

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

N :

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

TRACE :

if nonzero, the progression of the algorithm is shown (default : 0).

'plot':

if one input parameter is 'plot', tfrmh runs tfrqview. and TFR will be plotted

TFR :

time-frequency representation.

F :

vector of normalized frequencies.

Description

tfrmh computes the Margenau-Hill distribution of a discrete-time signal X, or the cross Margenau-Hill representation between two signals.

Examples

sig=fmlin(128,0.1,0.4); tfrmh(sig,1:128,128,1,'plot');
