Fourier transform for dummies - Mathematics Stack Exchange What is the Fourier transform? What does it do? Why is it useful (in math, in engineering, physics, etc)? This question is based on Kevin Lin's question, which didn't quite fit in MathOverflow An
How to calculate the Fourier Transform of a constant? The theory of Fourier transforms has gotten around this in some way that means that integral using normal definitions of integrals must not be the true definition of a Fourier transform
What is the Fourier transform of $f (t)=1$ or simply a constant? 1 I know that this has been answered, but it's worth noting that the confusion between factors of $2\pi$ and $\sqrt {2\pi}$ is likely to do with how you define the Fourier transform in the first place
Is Fourier series always used for periodic signals and Fourier . . . In our mathematics classes ,while teaching the Fourier series and transform topic,the professor says that when the signal is periodic ,we should use Fourier series and Fourier transform for aperiodic signals
Understanding Fourier transform example in Matlab I'm studying about Fourier series and transform and I get confused with the following Matlab example of Fourier transformation: Fs = 1000; % Sampling frequency T = 1 Fs;
