Ctfrpage

Page time-frequency distribution

Calling Sequence

[TFR,T,F] = Ctfrpage(X)
[TFR,T,F] = Ctfrpage(X, T)
[TFR,T,F] = Ctfrpage(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.

Examples

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

Description

Computes the Page distribution for a signal X.
