6. How We Compute Digital Signal Spectra
Computing Digital Spectra
One of the most important aspects of digital signal processing is the computation, and display on a computer screen, of the spectral amplitude of a digital signal as shown in Figure 6-1. The ability to examine the spectrum of a digital signal is as crucial to a signal processing engineer as a microscope is to a medical researcher.

Today, there are two primary methods available to compute digital signal spectra, and those two procedures have the fancy names of the discrete Fourier transform and the fast Fourier ...
