Aim: To find a mean and variance of a discrete random variable
Equipment:
PC with windows (95/98/XP/NT/2000).
MATLAB Software
MATLAB PROGRAM:
clear all;
close all;
x=[1 2 3 4 5 6];
n=length(x)
m = (1/n)*sum(x)
v = (1/n)*(xm)*(xm)'
RESULTS:
n = 6
m =3.5000
v = 2.9167
VIVA QUESTIONS
1. What is Signal Modeling.
Ans: Smallsignal modeling is a common analysis technique in engineering which is used to approximate the behavior of nonlinear devices with linear equations and signals.
2.Define Periodic and a periodic Signal.
Ans: If x(t)=x(t+T) then x(t) is periodic signal otherwise it is a periodic signal.
