Question

Create a new function called unitstep to produce the unit step function u(t): u(t) = 0 for t < 0, and u(t) = 1 for t ? 0. The function should take two parameters: a time vector Time that speci?es the ?nite range of t for the whole signal, and a time-shift value tshift that indicates where the unit step function changes value. Time can be any range, such as 0:25, -5:0.1:5, or linspace(-2,8,1000). The output should have the same dimensions as Time. tshift can be any scalar value (positive or negative). unitstep(Time, 0) should produce the unit step function as de?ned above. unitstep(Time, 4) should be equivalent to the delayed unit step u(t ? 4), unitstep(Time, -4) should produce u(t + 4).

Explanation / Answer

matlab program for producing unit step function
clc
clear all

a=input('the value of a= ')
b=input('the value of b= ')
m=input('the magnitude of impulse= ')
n=input('the impulse index= ')
for i=a:b
t(i)=i
if i==n
x(i)=1
else
x(i)=0
end
end
x=x*m
stem(t,x)
