Is there a name for the result of summing the bins of a DFT?
I don't mean to sum the squares of the bins, but to simply add the magnitude of the frequency bins together to get a single result.
Is there a special name that describes how this result would relate to the signal in the time-domain?
The best I can think of would be the total power across the DFT bandwidth, but I believe that is calculated by taking the root of the sum of the squares of the bins, per Parseval's theorem.
