How to plot different discrete signal using MATLAB

1.Introduction:-

Here we are going to plot
1) unit impulse function
2) unit step signal
3) Ramp signal
4) sine signal
5) rising exponential
6) decaying exponential

2.Problem Statement:-
To plot different discrete signal using MATLAB.


3.Program:-
clc;
close all;
clear all;
n=-10:10;
% unit impulse function
a=1*(n==0);
subplot(3,2,1)
stem(n,a)
xlabel('n discrete time')
ylabel('magnitude')
title('unit impulse')
% unit step function
b=1*(n>=0)+0*(n<0);
subplot(3,2,2)
stem(n,b)
xlabel('n discrete time')
ylabel('magnitude')
title('unit step')
% unit ramp function
c=n.*(n>=0)+0*(n<0);
subplot(3,2,3)
stem(n,c)
xlabel('n discrete time')
ylabel('magnitude')
title('unit ramp')
% unit sine function
f=7/8;
mag=1
d=mag*sin(2*pi*f*n);
subplot(3,2,4)
stem(n,d)
xlabel('n discrete time')
ylabel('magnitude')
title('sine function')
% rising exponential function
e=2.^(n);
subplot(3,2,5)
stem(n,e)
xlabel('n discrete time')
ylabel('magnitude')
title('rising exponential function')
% decaying exponential function
f=2.^(-n);
subplot(3,2,6)
stem(n,f)
xlabel('n discrete time')
ylabel('magnitude')
title('decaying exponential function')

4.How to use this code:-
Here you have to only copy the code to MATLAB and just run it the result will appear on figure window.

5.Output :-

 Figure Window  

                                     

6.Conclusion -
Here we have successfully plot the different discrete signal using MATLAB.
