The first part of the note emphasizes Fourier series, since so many aspects of harmonic analysis arise already in that classical context. This volume presents the real variable methods of Fourier analysis introduced by Caldern and Zygmund. They dealt with theta functions and the zeta function, giving the standard proof of the functional equation for the zeta function that uses Poisson summation. Fourier transform as a limiting case of Fourier series is concerned with non-periodic phenomena. truncating the sum over n after some low value n = N). 1 Review: The Fourier Transform 1.1 Properties of the Fourier transform This class is called \Classical Fourier Analysis," but for the past 20 years, it has been taught more like \Modern Harmonic Analysis."

Fourier analysis is the study of how general functions can be decomposed into trigonometric or exponential functions with denite frequencies. In mathematics, Fourier analysis ( / frie, - ir /) [1] is the study of the way general functions may be represented or approximated by sums of simpler trigonometric functions. FOURIER ANALYSIS 7 1.3.

Fourier analysis encompasses a variety of perspectives and techniques. Today, Fourier analysis is, among other things, perhaps the single most important mathematical tool used in what we callsignal processing.It represents the fundamental procedure by which complex physical "signals" may be decom- posed into simpler ones and, conversely, by which complicated signals may be created out of simpler building blocks. But as it has been mentioned you need Calculus.
