Unit Step Signal

Matlab program to generate Unit Step Sequence/Signal in discrete and continuous form.

Matlab code

clc;

clear all;close all;

n=input('Enter the length of the Unit Step Sequence N=');
t=0:n-1; % defines the time axis

u=ones(1,n); % defines an 1 x n matrix which is filled with ones

subplot(2,1,1);

plot(t,u);

axis([0 n+5 -2 2]);

ylabel('u(t)');

xlabel('Time->');

title('Graph for Unit Step Sequence [Continuous form]'); grid;

subplot(2,1,2);

stem(t,u);

axis([0 n+5 -2 2]);

ylabel('u[t]');

xlabel('Time->');

title('Graph for Unit Step Sequence [Discrete form]');
