FM Demodulation with Feedback: Exploring Threshold Reduction Mechanisms

FM Demodulation with Feedback: Exploring Threshold Reduction Mechanisms

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.


Exploring the Threshold Constraints of FM Demodulation Through Solved Examples

Exploring the Threshold Constraints of FM Demodulation Through Solved Examples

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.
