Q217 : Magnitude of Signal at the End of the Time Window

Question
Since the time-domain signal in FFTSES is assumed to be periodic, how large can be the difference between the signal at the beginning of the time-window and the signal at its end?


Answer
This difference should be small compared to the maximum value of the signal in the time window: the error introduced by this difference should be on the order of the ratio of the difference and the maximum value.
