Signal- to- noise ratio (SNR) is a key metric in commulation systems, especially in systems that use modulation techniques. It measures thee level of thee desired signal relative to background noise, impacting te quality and reliability of data transmission. This article diquises praktical method calculating SNR in modulated systems.

Understanding Signal- to- Noise Ratio

SNR is typically expressed in decibels (dB). A higer SNR indicates a clearer signal with less noise interfece. In modulated systems, SNR influence thoe choice of modulation scheme and error correction techniques.
