tfrri

Rihaczek time-frequency distribution.

Calling Sequence

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

Parameters

X :

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

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', tfrri applies TFRQVIEW on the real part of the distribution, which is equal to the Margenau-Hill distribution.

TFR :

time-frequency representation.

F :

vector of normalized frequencies.

Description

tfrri computes the Rihaczek distribution of a discrete-time signal X, or the cross Rihaczek representation between two signals.

Examples

sig=fmlin(128,0.1,0.4); tfrri(sig,'plot');
