Fourierplan
Fourierplan is a term that sometimes appears in discussions related to signal processing and the Fourier Transform. It generally refers to the visual representation of a signal's frequency content, specifically its magnitude and phase as a function of frequency. When one speaks of the "Fourierplan," they are often alluding to the complex-valued output of the Fourier Transform, which can be visualized in a two-dimensional plane.
The horizontal axis of this plane typically represents frequency, while the vertical axis can represent either
