Computation of energy of rectangular pulse
Aim: Computation of energy of rectangular pulse
PC with windows OS.
MATLAB Software
%This Program generates a rectangular pulse and finds its energy
f=input('enter the sampling frequency')
T=1/f;
t=T:T/f:T;
x=zeros(1,length(t));
c=input('enter the duration of the rectangular pulse in terms of number of samples to included')
i=find(t==0);
x(i:i+c1)=0.25;
E=sum(x.*x);
plot(t,x)
xlabel('time')
ylabel('amplitude')
