Abstract: : Noise in radio frequency (RF) communication systems, such as thermal noise and interference from nearby channels, often disrupts signal clarity and lowers the signal-to-noise ratio (SNR). In this paper, we focus on tackling this problem by designing a finite impulse response (FIR) digital filter to effectively reduce noise and enhance signal quality. The filter is tailored to suppress high-frequency noise while ensuring the desired signal remains intact. Through simulations, we evaluated the filter’s performance in both time and frequency domains. The results showed a significant boost in SNR, from 18 dB to 35 dB, after filtering. The frequency response of the filter successfully attenuated unwanted noise above the 200 kHz cutoff, and its computational efficiency makes it practical for real-time applications. Keywords: RF communication, noise reduction, FIR filter, signal-to-noise ratio (SNR), interference, digital signal processing, real-time applications.
