klauder

Klauder wavelet in time domain

Calling Sequence

X = klauder(N)
X = klauder(N, LAMBDA)
X = klauder(N, LAMBDA, F0)

Parameters

N :

a positive scalar with integer value: the number of points in time

LAMBDA :

a positive scalar: the attenuation factor or the envelope (default : 10)

F0 :

a scalar in [0 0.5]: the central frequency of the wavelet (default : 0.2)

X :

a real column vector of size N: the klauder time samples.

Description

klauder generates the KLAUDER wavelet in the time domain K(f) = e^{-2.pi.LAMBA.f} f^{2.pi.LAMBDA.F0-1/2}

Examples

x1 = klauder(128); 
x2 = klauder(128,5,0.01);
clf; plot([x1 x2]);
legend("lambda=10, f0=0.2","lambda=5,  f0=0.01");
