FMVerhältnis

FMVerhältnis, short for Frequenzmodulationsverhältnis, is a term used in the field of telecommunications and signal processing to describe the ratio of the frequency deviation to the modulating signal frequency. It is a key parameter in frequency modulation (FM) systems, which are used in various applications such as radio broadcasting, telecommunications, and radar systems.

The FMVerhältnis is defined as the ratio of the peak frequency deviation (Δf) to the maximum frequency

FMVerhältnis = Δf / fm

Where:

- Δf is the peak frequency deviation, which is the maximum amount by which the carrier frequency

- fm is the maximum frequency of the modulating signal.

A higher FMVerhältnis indicates a larger frequency deviation for a given modulating signal frequency, resulting in
