MATLAB Program for the Generation of Circular Convolution

 GENERATION OF CIRCULAR CONVOLUTION:

To write a program for the generation of Circular convolution for the given sequence by using MATLAB.

ALGORITHM:

Step 1: Start
Step 2: Read the first sequence
Step 3: Read the second sequence
Step 4: Find the length of first sequence
Step 5: Find the length of second sequence
Step 6: Perform circular convolution for both the sequences
Step 7: Plot the sequence
Step 8: Display the output sequence
Step 9: Stop
PROGRAM:

clc;

g=input('Enter the sequence 1:');

h=input('Enter the sequence 2:');

N1=length(g);

N2=length(h);

N=max(N1,N2);

N3=N1-N2;

if(N3>0)

    h=[h,zeros(1,N3)];

else

    g=[g,zeros(1,-N3)];

end

for n=1:N;

    y(n)=0;

    for i=1:N;

        j=n-i+1;

        if(j<=0)

            j=N+j;

        end

        y(n)=[y(n)+(g(i)*h(j))];

    end

end

disp('The resultant is');y

subplot(2,1,1);

stem(y);

xlabel('N->');

ylabel('Amplititude->');
