Fourier analysis began with trying to understand when it was possible to represent general functions by sums of simpler trigonometric functions.
The attempt to understand functions (or other objects) by breaking them into basic pieces that are easier to understand is one of the central themes in Fourier analysis.
Fourier analysis is named after Joseph Fourier who showed that representing a function by a trigonometric series greatly simplified the study of heat propagation.

What is a function of fourier analysis?
It is to convert a function into a sum of sine (or cosine) functions so as to simplify its analysis.
Fourier analysis shows that the saw tooth wave consists of which type of wave?
Fourier analysis shows that the saw wave is constructed through manipulation of a sine wave, I can't remember the maths behind it but it's definitely a sine wave.
Why short time Fourier transform is necessary?
The Short-Time Fourier Transform (STFT) is necessary because it allows for the analysis of non-stationary signals, where the frequency content changes over time. By dividing a signal into shorter segments and applying the Fourier Transform to each segment, STFT provides a time-frequency representation that captures how the frequency characteristics evolve. This is crucial in applications like speech processing, music analysis, and biomedical signal analysis, where understanding the time-varying nature of signals is essential for accurate interpretation and processing.
How you can use fourier analysis in the communication?
Fourier analysis is used in communication systems to analyze and process signals by decomposing them into their frequency components. This allows for the effective modulation and demodulation of signals, enabling clearer transmission over various media. Additionally, it aids in filtering out noise and optimizing bandwidth usage, improving the quality and efficiency of data transmission in applications such as radio, television, and digital communication.

What is Fourier analysis consisting of?
The general field of Fourier analysis is often known as harmonic analysis. The Fourier analysis it occurs in the modeling time-dependent phenomena such as speech, EKGs, EEGs, earthquakes and tides. Examples also include the study of vibrations and circular, physical and rectangular pictures. It also involves the transmission of pictures including the weather or pictures of remote planets taken by space probes.
