Dft indices
WebThe indices for the input samples (n) and the DFT output samples (m) always go from 0 to N–1 in the standard DFT notation. This means that with N input time-domain sample values, the DFT determines the spectral … WebAug 23, 2016 · 1. I have been trying to understand Discrete Fourier Time Series (NOT Transform). It is defined as. a k = ∑ n = 0 N − 1 x [ n] e j k 2 π N n. where N is the Time period and an integer (by definition), and n goes from 0... N − 1. Fair enough. But when N = 0.2 second as the time period of the wave, then how we define n, as N − 1 is negative.
