Computation of Energy of sinusoidal signal
Aim: Computation of Energy of sinusoidal signal
Equipments:
PC with windows OS.
MATLAB Software
% Program generates a sinusoidal Pulse and computes its Energy
f=input('enter the value of the frequency')
T=1/f;
t=0:T/f:T;
x=(sin(2*pi*f*t));
x1=abs(x);
E1=x1.*x1;
E=sum(E1);
plot(t,x)
xlabel('time')
ylabel('amplitude')
title('Sinusoidal signal')
disp('Energy of the generated signal in joules is')
disp(E)
Result:
enter the value of the frequency100
f = 100
