The Fourier Transform for the sine function can be established just as quickly using Euler"s identity for the sine function: The an outcome is: keep in mind that the Fourier Transform the the genuine function, sin(t) has an imagine Fourier Transform (no genuine part). This is characteristics of odd functions.

Fourier change of sin (Wt) quite worksheet, Jean. One comment around the DFT: the advantage of the DFT is the it permits to calculate spectral materials at any kind of frequency, contrary to the FFT (given a fixed number of samples). The FFT is usefull to acquire a complete spectrum sampling in one shot. The DFT permits to emphasis on a certain frequency.
