MODE

Time-limited Functions Are Not Band-limitedctly supported—if it is zero outside of some bounded region—then its Fourier transform cannot be compactly supported. Then we show that the “narrower” a function is in the time domain, the more spread out it will be in the frequency domain (and .).

Inertia

Windowing. This “truncation” of the signal changes the Fourier transform—the spectrum—of the signal. In this chapter, we learn about .; we learn how to control the effect that truncation has on a signal’s spectrum.

The General Structure of Sampled-data Systemssis of discrete-time signals as in Part I or to implement digital filters as in Part III—one must sample an analog signal, and often one must convert digitized samples of a signal back into an analog signal. Understanding how these conversions are made is the purpose of this part of the book—of Part II.
