What are the technique in reducing of noise in FM?

To reduce noise in Frequency Modulation (FM) signals, techniques such as pre-emphasis and de-emphasis can be employed. Pre-emphasis boosts higher frequencies before transmission, while de-emphasis reduces them at the receiver, improving the signal-to-noise ratio. Additionally, the use of limiters can help eliminate amplitude variations caused by noise, ensuring that only the frequency variations are decoded. Finally, implementing digital signal processing techniques, such as filtering and error correction algorithms, can further enhance noise reduction in FM systems.
