Akin to a convolution or a Gabor filter we transform from physical to spectral in a way that respects the uncertainty limit.
Steps:
1. FT
Fourier transform one physical signal into a spectrum with …

Is there a way to work with Fourier and BigFloat? It goes via FFTW which is causing some issues.
```
using ClassicalOrthogonalPolynomials
F = Fourier{BigFloat}()
F[:, 1:10] \ sin.(axes(F,1))
``…

Sunny currently returns all intensities in Fourier space (momentum $\mathbf{q}$ and energy $\omega$). There should be convenience functions get Fourier transformed intensities in real-space $\mathbf{r…

Hello, Fourier transform generally processes grayscale images, so how do you use Fourier transform to remove high-frequency components of RBG images? Is the input of the HighFreqSuppress instance a th…

### Typo Details:
Are these supposed to have commas between the entries? Right now it looks like multiplication
### Suggested Fix:
Just add commas between them

Related to https://github.com/phetsims/fourier-making-waves/issues/76... We're running into a problem with “play area” and “control area” for the Wave Game screen in Fourier. This problem is not spe…

Currently these are called `stft_obj` in the code, and they are xarrays.
There is now a class called Spectrogram() as a container for these objects. This could be where the interface to mth5's Fo…

A PhET-iO version was not part of the plan for the Fourier 1.0 release. But the reality is that it's pretty much impossible (or very unwise) to do sim development without considering PhET-iO, and doi…
