Chapter 10. Fourier Analysis of Discrete-Time Signals and Systems
Diligence is the mother of good luck.
Benjamin Franklin (1706–1790) Printer, inventor, scientist, and diplomat
I am a great believer in luck, and I find the harder I work, the more I have of it.
President Thomas Jefferson (1743–1826) Main author of the U.S. Declaration of Independence
In this chapter we will consider the Fourier representation of discrete-time signals and systems. Similar to the connection between the Laplace and the Fourier transforms of continuous-time signals and systems, if the region of convergence of the Z-transform of a signal or of the transfer function of a discrete system includes the unit circle, then the discrete-time Fourier transform ...
