How do you solve a Fourier transform question?
a really basic use of a fourier transform is with a sound wave. so talking music all of these sound waves are essentially just signals that we hear the way the soundwaves. works is a difference in pressure um in the air which causes different vibrations. and we can pick up these vibrations as different amplitudes.What is practical example of Fourier transform?
Fourier Transform is a mathematical model which helps to transform the signals between two different domains, such as transforming signal from frequency domain to time domain or vice versa. Fourier transform has many applications in Engineering and Physics, such as signal processing, RADAR, and so on.What is Fourier transform used to solve?
Taking the Fourier transform, we find: F(?(x,t=0))=?(x?2). The Fourier transform is 1 where k = 2 and 0 otherwise. We see that over time, the amplitude of this wave oscillates with cos(2 v t). The solution to the wave equation for these initial conditions is therefore ?(x,t)=sin(2x)cos(2vt).

FOURIER TRANSFORMS
2.1 Introduction
The Fourier series expresses any periodic function into a sum of sinusoids. The Fourier transform is the extension of this idea to non-periodic functions by taking the limiting form of Fourier series when the fundamental period is made very large (infinite). Fourier transform finds its applications in astronomy, signal processing, linear time invariant (LTI) systems etc. Some useful results in computation of the Fourier transforms:1.
