WebFeb 19, 2012 · When dealing with Fourier analysis, you need to be careful with terminology. The fast Fourier transform (FFT) is an efficient implementation of the discrete Fourier Transform (DFT). There is also the discrete-time Fourier transform (DTFT) which under some stimulus conditions is identical to the DFT. WebTo place the frequency samples in ascending order we shall use x = ff t sh i f t (τ ∗ ff t (x)), which will give us the CTFT evaluated at − π / τ + 2 πk / N τ for 0 ≤ k ≤ N − 1. In this exercise you will approximate the CTFT of x (t) = e − 2 ∣ l using ff t and a truncated version of x (t). a) Find an analytical expression for ...
