DFT stands for Discrete Fourier Transform. While the Fourier transform integrates functions over real numbers, the DFT is an operation that transforms a function $${f}$$ on $${ \{ 0, 1, ... N-1 \} }$$ ...

When studying physics at university, you occasionally encounter the Fourier transform suddenly in various places. It seems that at some universities, it is taught in the first year, but it appears to ...
