Fourier analysis is the process of obtaining the spectrum of frequencies H(f) comprising a time-series h(t) and it is realized by the Fourier Transform (FT). Fourier analysis converts a time series from its original domain to a representation in the frequency domain and vice versa. In the early 1800's Joseph Fourier determined that such a function can be represented as a series of sines and cosines. In other words he showed that a function Even Square Wave (Exponential Series). Consider, again, the pulse function.

A A Fourier series is a way of representing a periodic function as a (possibly infinite) sum of sine and cosine functions.

It is faster to compute Fourier series of a function by using shifting and scaling on an already computed Fourier series rather than computing again.

FOURIER SERIES AND INTEGRALS 4.1 FOURIER SERIES FOR PERIODIC FUNCTIONS This section explains three Fourier series: sines, cosines, and exponentials eikx. Square waves (1 or 0 or −1) are great examples, with delta functions in the derivative. We look at a spike, a step function, and a ramp—and smoother functions too.

Assuming you’re unfamiliar with that, the Fourier Series is simply a long, intimidating function that breaks down any periodic function into a simple series of sine & cosine waves. the Fourier series becomes and if we further let in the second sum, we obtain This is the complex form of the Fourier series, which contains, in an attractive and economical package, the same information as Eq. (7.1). Definition of Fourier Series and Typical Examples Baron Jean Baptiste Joseph Fourier (1768−1830) introduced the idea that any periodic function can be represented by a series of sines and cosines which are harmonically related.
