Computation of Average Power
Aim: Computation of Average Power
Equipments:
PC with windows OS.
MATLAB Software
This program generates a Periodic sinusoidal signal and computes its average power
f=input('enter the frequency of the signal');
i=input('enter the no.of cycles to be plotted')
T=i/f;
t=0:T/f:T;
x=sin(2*pi*f*t);
y=input('enter the number of cycles(<=i) over which average power is to be computed')
z=(length(t)1)/i;
x1=abs(x);
x2=x1.*x1;
p=(1/(y*z))*sum(x2(1:y*z));
plot(t,x)

Result:
enter the frequency of the signal100
enter the no.of cycles to be plotted2
i =2
enter the number of cycles(<=i) over which average power is to be computed2
y =2
The average power of the generated signal measured in watts is
