Abstract
The DFT is an approximation to the Fourier transform of a signal. The input to the DFT is always a sequence of samples taken over a finite time period. This “truncation” of the signal changes the Fourier transform—the spectrum—of the signal. In this chapter, we learn about windowing; we learn how to control the effect that truncation has on a signal’s spectrum.
