Say I have a function $f(x)$ that is given explicitly in its functional form, and I want to find its Fourier transform. If $f$ is too complicated to have an analytic expression for $\hat f(k)$, how ...
I'm trying to find out if it's possible to find the beat of a tune by Fourier analysis with Mathematica. I'm taking a 44.1 kHz sample sound and hoping that I might get a nice peak for a frequency ...
Introduction I have a greyscale photograph that I want to partition into areas of equal intensity. This means, that the integral over each partition should be (roughly) equal. There is no unique ...
In MATLAB there's a function called phase that is just like our Listable friend Arg, but ...
I'm trying to display the output response of a transfer function in Mathematica with and without a compensator. The problem is very strange: while the transfer function compensate is showing well, the ...
