Linear Filtering with DFT Methods by Pratik Thakre is a document available to read on EtoBox.
1. The discrete Fourier transform (DFT) can be used to implement linear filtering by performing circular convolution in the frequency domain after zero-padding the input and filter sequences. 2. The overlap-save and overlap-add methods allow linear filtering to be performed on real-time signals in blocks while maintaining continuity between blocks. 3. For circular convolution to equal linear convolution, the DFT size N must be greater than or equal to the length of the input plus the filter minus one (N
