[y](#mw%5Fbf348f0b-663a-4397-ac92-d0896113fdcb) = rectpuls([t](#mw%5Fb66668a4-9cc9-4dcf-a4be-8ae23c5fa07a)) returns a continuous, aperiodic, unit-height rectangular pulse at the sample times indicated in arrayt, centered about t =0.

example

Examples

collapse all

Generate 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) ylim([-0.2 1.2])

Input Arguments

collapse all

Sample times of unit rectangular pulse, specified as a vector.

Data Types: single | double

Rectangle width, specified as a positive number.

Output Arguments

collapse all

Rectangular pulse of unit amplitude, returned as a vector.

Note

The interval of nonzero amplitude is defined to be open on the right, that is,rectpuls(-0.5) = 1 whilerectpuls(0.5) = 0.

Tips

rectpuls can be used in conjunction with the pulse train generating function pulstran.
