Fourier Analysis

Overview

Fourier analysis (named after Joseph Fourier) is a type of analysis which seeks to express an given function as a sum (or integral) of sine and cosine functions.

Topics

• Fourier Series : expresses a function as the sum of an (possibly) infinite number of sine and cosine functions.
• Fourier Transform : expresses a function as an integral over a complex exponential (sines and cosines)
