CNR

CNR, or Channel-to-Noise Ratio, measures the strength of a desired signal relative to background noise in a communication system. It indicates how clearly information can be received; a higher CNR means the signal stands out more prominently against the noise, leading to better quality and fewer errors. Think of it as the difference in volume between the music you want to hear and the background hiss. Maintaining a high CNR is essential for reliable data transmission, whether in broadcasting, satellite links, or wireless networks.
