Fourier Analysis and the Discrete Fourier Transform signal’s samples. In this chapter, we introduce the discrete Fourier transform, we discuss its significance, and we derive its properties. Then we discuss the family of algorithms know as fast Fourier transforms. We explain their significance, describe how one uses them, and discuss zero-padding an

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 Spectral Analysis of Random Signalstle down” no matter how long a sequence one measures. In this chapter, we present a brief overview of the difficulties inherent in analyzing the spectra of random signals, and we give a quick survey of a solution to the problem—the method of averaged periodograms.

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

A Simple Digital to Analog Converternvert the inputs into an analog output signal. (Often the “ones” are a reference voltage, . and the “zeros” are 0V.) In this chapter, we present one simple, albeit not very practical, DAC. This DAC can be used with many types of microprocessors and can be considered a purely passive DAC.
