amgauss

Generate gaussian amplitude modulation.

Calling Sequence

Y=amgauss(N)
Y=amgauss(N,T0)
Y=amgauss(N,T0,T)

Parameters

N :

number of points.

T0 :

time center (default : N/2).

T :

time spreading (default : 2*sqrt(N)).

Y :

signal.

Description

amgauss generates a gaussian amplitude modulation centered on a time T0, and with a spread proportional to T. This modulation is scaled such that Y(T0)=1 and Y(T0+T/2) and Y(T0-T/2) are approximately equal to 0.5 .

Examples

z=amgauss(160); plot(z);
z=amgauss(160,90,40); plot(z);
z=amgauss(160,180,50); plot(z);
