To develop program for discrete correlation USING DSP PROGRAM


AIM: - To develop program for discrete correlation

PROGRAM: -

%Program for computing cross correlation of the sequences x=[1,2,3,4] and h=[4,3,2,1]
clc;
clear all; 
close all;
x=input('enter the 1st sequence');
h=input('enter the 2nd sequence');
y=xcorr(x,h);
figure;
subplot(3,1,1);
stem(x);
ylabel('Amplitude-->');
xlabel('(a)n-->');
subplot(3,1,2)
stem(h);
ylabel('Amplitude-->');
xlabel('(b)n-->');
subplot(3,1,3)
stem(fliplr(y));
ylabel('Amplitude');
xlabel('(c)n-->');
disp('The resultant signal is');
fliplr(y)

Output: -

enter the 1st sequence[1 2 3 4]
enter the 2nd sequence[4 3 2 1]


The resultant signal is

ans =

   16.0000   24.0000   25.0000   20.0000   10.0000    4.0000    1.0000
