S discussed in Chapter 8, the Fast Fourier Transform (FFT) allows us to transform a
discrete-time signal from the sample (i.e., time) domain to the frequency domain. It
is useful and often necessary to view the frequency content of a signal, and test equipment
manufacturers market spectrum analyzers costing many thousands of dollars to perform
this task. Nearly any engineer or technician working, for example, with communications or
audio systems such as satellite up/down links, cellular telephone networks, radio/television
stations, home theaters, or any high-end sound system must be able to analyze ...
