Ctfrppage

Pseudo Page time-frequency distribution

Calling Sequence

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

Parameters

T = time instant(s) (default :

1:length(X)).

N = number of frequency bins (default :

length(X)).

H = frequency smoothing window (default :

Hamming(N/4)).

Description

Computes the pseudo Page distribution for 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] = Ctfrppage(x,t,128);
grayplot(T,F,tfr');
xlabel time
ylabel frequency
