amrect

Purpose

Rectangular amplitude modulation.

Synopsis

y = amrect(N)
y = amrect(N,t0)
y = amrect(N,t0,T)

Description

amrect generates a rectangular amplitude modulation centered on a time t0, and with a spread proportional to T. This modulation is scaled such that y(t0)=1.

Name	Description	Default value
N	number of points
t0	time center	N/2
T	time spreading	2*sqrt(N)
y	signal

Examples

         z=amrect(160);        plot(z);
         z=amrect(160,90,40);  plot(z);
         z=amrect(160,180,70); plot(z);
