What are the applications of frequency modulation?

Frequency modulation (FM) finds applications in telecommunications, radio broadcasting, and signal processing. Its ability to resist amplitude variations makes it resilient to noise, improving signal quality. FM is used in wireless communication systems, radar, music synthesis, and high-fidelity audio transmission due to its efficiency in preserving signal integrity over long distances.

How to Calculate SNR for FM System?

SNR for FM System calculator uses SNR of FM System = 3*Deviation Ratio^2*Amplitude of Message Signal*Signal to Noise Ratio to calculate the SNR of FM System, The SNR for FM System formula is defined a signal-to-noise ratio, often written S/N or SNR, is a measure of the strength of the desired signal relative to background noise (undesired signal). A ratio higher than 1:1 indicates more signal than noise. SNR of FM System is denoted by SNR_fm symbol.
