tfrrppag

Reassigned pseudo Page time-frequency distribution.

Calling Sequence

[TFR,RTFR,HAT] = tfrrppag(X)
[TFR,RTFR,HAT] = tfrrppag(X,T)
[TFR,RTFR,HAT] = tfrrppag(X,T,N)
[TFR,RTFR,HAT] = tfrrppag(X,T,N,H)
[TFR,RTFR,HAT] = tfrrppag(X,T,N,H,TRACE)
[TFR,RTFR,HAT] = tfrrppag(...,'plot')

Parameters

X :

analysed signal,

T :

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

N :

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

H :

frequency smoothing window, H(0) being forced to 1 (default : Hamming(N/4)).

TRACE :

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

'plot':

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

TFR, :

time-frequency representation and its reassigned

HAT :

Complex matrix of the reassignment vectors.

Description

tfrrppag computes the pseudo Page distribution and its reassigned version. When invoked without left hand arguments, TFRRPPAG runs TFRQVIEW.

Examples

sig=fmconst(128,0.2); t=1:128;
h=tftb_window(65,'gauss'); tfrrppag(sig,t,128,h,1,'plot');
