To find a mean and variance of a discrete random variable
Aim: To find a mean and variance of a discrete random variable
PC with windows (95/98/XP/NT/2000).
x=[1 2 3 4 5 6];
m = (1/n)*sum(x)
v = (1/n)*(x-m)*(x-m)'
n = 6
v = 2.9167
1. What is Signal Modeling.
Ans: Small-signal 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.
