How do you convert circular convolution to linear convolution?

For the circular convolution of x and y to be equivalent, you must pad the vectors with zeros to length at least N + L - 1 before you take the DFT. After you invert the product of the DFTs, retain only the first N + L - 1 elements. Create two vectors, x and y , and compute the linear convolution of the two vectors.

What does zero padding do while solving linear convolution using circular convolution?

what does zero padding do while solving linear convulation using circular convulation? Zero-padding avoids time-domain aliasing and make the circular convolution behave like linear convolution.

Why zero padding is used in circular convolution?

Zero padding allows one to use a longer FFT, which will produce a longer FFT result vector. A longer FFT result has more frequency bins that are more closely spaced in frequency.

What is zero padding linear convolution?

Zero padding is a technique typically employed to make the size of the input sequence equal to a power of two. In zero padding, you add zeros to the end of the input sequence so that the total number of samples is equal to the next higher power of two.
