Procedure:-
1. Enter the sequence x
2. Enter the sequence y
3. Find the lengths of x and y,ie;Nx and Ny respectively
4. Check Nx=Ny:proceed if equal
5. Initialize a loop variable number of output points
6. For each out sample , access the samples of y in the cyclic order
7. Find the sum of products of x and cyclically folded and shifted y
Description:-
Steps for Cyclic Convolution
Steps for cyclic convolution are the same as the usual convolution, except all index calculations are done mod N = on..............etc

circular convolution using dft and idft matlab,
circular convolution using dft and idft theory,
compute the circular convolution of the following sequences using dft and idft h n 1 2 3 4 x n 1 2 2 1,

circular convolution using dft and idft in matlab,
linear convolution of two sequences using both dft and idft,

Procedure:-
1) Find the length of the first sequence x=x_length
2) Find the length of the first sequence h=h_length
3) Take the circular convolution order as N
4) If x_length < N, pad enough number of zeros to x, so that the number of samples in the modified x=N
5) If h_length < N ,pad enough number of zeros to h, so that the number of samples in the modified h=N
6) Take DFT for modified x=x(k)
7) Take DFT for modified h=H(k)
8) Compute Y(K)=X(K)*H(K)
9) Compute y(n)=IDFT(Y(k))
10) Verify if y=conv(x,..............etc
