Introduction to the Threshold Effect in FM Systems

Introduction to the Threshold Effect in FM Systems

The standard FM SNR equation breaks down once the carrier-to-noise ratio drops below a critical threshold, revealing a hard limit on trading bandwidth for noise performance.


SNR Analysis of FM Modulation with Arbitrary Message Signals

SNR Analysis of FM Modulation with Arbitrary Message Signals

Deriving a general signal-to-noise expression for frequency modulation with any message signal reveals a core trade-off: more deviation buys better noise performance, but only by using more bandwidth.
