## MATLAB Program for M-point moving average filter

Hi friends, today we are going to learn a how to write a MATLAB program for m point moving averagr filter.

Steps for writing M-point moving average filter program in MATLAB:

- Take a given signal 2n*(0.9)^n and denote it by s(n).
- Then generate a random noise signal having same length (50) as that of s(n) and denote it by d.
- Then add s+d and save it in p, i.e. p=s+d.
- We know that the formula for m point moving average filter is given by

- To determine summation use one for loop.
- Finally divide summation by M, you will get original signal.

### The MATLAB program:

clc; clear all; close all; n=1:50; s(n)=2*n.*(0.9).^n; subplot(2,2,1) stem(s) xlabel('Original signal') d=rand(1,50); subplot (2,2,2) stem(d) xlabel('Noise signal') p=s+d; subplot (2,2,3) stem(p) xlabel('Corrupted Signal') m=100; xu=0; for i=1:m d=rand(1,50); x=s+d; xu=xu+x; end xu=xu/m; subplot(2,2,4) stem(xu) xlabel('Output signal')

OUTPUT of M-Point moving average filter :
