Interference, Pre-Emphasis, and the Capture Effect in FM and PM Systems

Interference, Pre-Emphasis, and the Capture Effect in FM and PM Systems

Interference in FM grows stronger with frequency offset, until pre-emphasis flattens the curve. See why a signal just twice as strong as a rival broadcast can completely capture the channel.


The Benefits and Limitations of Pre-Emphasis and De-Emphasis in FM Noise Reduction

The Benefits and Limitations of Pre-Emphasis and De-Emphasis in FM Noise Reduction

Pre-emphasis and de-emphasis boost noise performance in FM, but only up to a point—push the gain too far and you risk overmodulation.
