WebHere's my take on it. Let's conceptually think about what DFT means in signal processing sense, not just purely as a transform. In this case, it seems to me that applying DFT to a signal and to a system makes us wish to see different results. For example, let's apply the DFT to a constant signal of value 1. WebAnother way of viewing processing gain is to consider that the DFT performs a change of coordinates on the observations such that all of the signal energy ``piles up'' in one …
