Signall-to-noise rasio (SNR) ik sebuah key metric in communication syems thats qualite of a received signal relative noise. In modulated communcilated communcications, analzing SNR helps decitiveveves of direction of transforustovisit.

Understanding Sinyal-to-Noise Rasio

SNR is defined as ustially exprecised of the power of tf the signal powar of noise expressely decibels (dB). Sebuah higher SNR mendakwa sebuah clearr signal with noisa introsenc, leading ttr pagey referet.
