By closing a feedback loop around the demodulator, the FMFB architecture narrows the noise bandwidth and lowers the FM threshold, without improving SNR at high CNR.
Working through examples shows how the threshold effect reshapes FM design choices. See how ignoring it can undershoot the required carrier power by over 5x for the same target SNR...
Explore how frequency-modulated waves resist interference. We break down the demodulator architecture and derive the exact output signal power for a sinusoidal message.
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 u...
