rectpuls() - Signal Processing

y = rectpuls(t) returns
a continuous, aperiodic, unity-height rectangular pulse at the sample
times indicated in array t, centered about t = 0 and with a default
width of 1. Note that the interval of nonzero amplitude is defined
to be open on the right, that is, rectpuls(-0.5) = 1 while rectpuls(0.5) = 0.y = rectpuls(t,w) generates
a rectangle of width w.rectpuls is typically used in conjunction
with the pulse train generating function pulstran.

Syntax

y = rectpuls(t)y = rectpuls(t,w)

Example

Generate and Displace Rectangular PulseOpen This ExampleGenerate 200 ms of a rectangular pulse with a sample rate of 10 kHz and a width of 20 ms.fs = 10e3;
t = -0.1:1/fs:0.1;

w = 20e-3;

x = rectpuls(t,w);
Generate two copies of the same pulse:One displaced 45 ms into the past.tpast = -45e-3;
xpast = rectpuls(t-tpast,w);
One displaced 60 ms into the future and half as wide.tfutr = 60e-3;
xfutr = rectpuls(t-tfutr,w/2);
Plot the original pulse and the two copies on the same axes.plot(t,x,t,xpast,t,xfutr)
