Fourier analysis is the study of how general functions can be decomposed into trigonometric or exponential functions with deﬂnite frequencies. There are two types of Fourier expansions: † Fourier series: If a (reasonably well-behaved) function is periodic, then it can b Fourier analysis is the study of frequency compositions of a signal or image. The Fourier transform is the fundamental technique of Fourier analysis, and it decomposes the original data into its frequency components, which is often referred to as the frequency spectrum. Mathematically, the Fourier transform is represented as Fourier Transform series analysis, but it is clearly oscillatory and very well behaved for t>0 ( >0). 2 Fourier Transform 2.1 De nition The Fourier transform allows us to deal with non-periodic functions. It can be derived in a rigorous fashion but here we will follow the time-honored approac Fourier analysis is a method of representing general functions by approximate sum of simple trigonometric functions. The method is named after mathematician Jean Baptiste Joseph Fourier who formulated and proved the Fourier series. Fourier analysis is used in electronics, communications and acoustics

What is Fourier Analysis? Fourier Analysis is an extension of the Fourier theorem, which tells us that every function can be represented by a sum of sines and cosines from other functions Fourier analysis is now also used heavily in communication, thermal analysis, image and signal processing, quantum mechanics and physics. Fourier noticed that you can create some really interesting looking waves by just summing up simple sine and cosine waves. For example the wave in Figure 1, is a sum of the three sine waves shown in Figur

Fourier analysis plays a key role in the study of signals. For example consider the function of time shown at the left below (the vertical axis is arbitrary). If you play the signal (controls are below the image) you will hear the word hello. The signal is quite complicated as you can see by a detail of the image (from 0.30 to 0.35 seconds is. A Fourier series is that series of sine waves; and we use Fourier analysis or spectrum analysis to deconstruct a signal into its individual sine wave components.
