Pre-emphasis and De-emphasis Filtering in FM Systems

Pre-emphasis and De-emphasis Filtering in FM Systems

Simple first-order pre-emphasis and de-emphasis filters can boost FM receiver SNR by more than 13 dB by exploiting the spectral differences between signal and noise.


FM Threshold-Extended Demodulators: Insights on FMFB and PLL-Based Designs

FM Threshold-Extended Demodulators: Insights on FMFB and PLL-Based Designs

Worked examples quantify just how much the FMFB loop shrinks noise bandwidth. We also show how the PLL demodulator offers a simpler alternative for reducing threshold.
