Thanks a lot, Slartibartfast. I get what you are saying but by confusion was, well, at the end we are calculating DFTs of a new sequence constructed using the alternate...

Thanks rbj. I totally agree to your SE post. I also would like to think DFT exactly in the same way as DFS because the modular arithmetic related to DFT essentially...

Aliasing in Radix-2 FFT - Decimation in time

New thread started 6 years ago
Hi,We know for Radix-2 FFT, an N-point DFT is broken down to multiple 2-point DFTs. In doing so, one of the methods is to decimate in time, i.e., subsequent downsampling...
