SNR is imperative to distinguish various output signals to achieve efficient output. Signal-to-Noise Ratio is typically expressed in terms of decibels. The higher the SNR value, the better is the output. The reason is that there's more useful information (signal) than unwanted data (noise) in a high SNR output.

What is a good signal-to-noise ratio?
Generally, a signal with an SNR value of 20 dB or more is recommended for data networks where as an SNR value of 25 dB or more is recommended for networks that use voice applications. Learn more about Signal-to-Noise Ratio.
Why is higher SNR better?
SNR directly impacts the performance of a wireless LAN connection. A higher SNR value means that the signal strength is stronger in relation to the noise levels, which allows higher data rates and fewer retransmissions – all of which offers better throughput.
What is signal-to-noise ratio and why is it important to know this value in your patient's classroom?
The difference between the loudness of a teacher's voice and the background noise level is described by signal-to- noise ratio (SNR). SNR is a critical component of classroom acoustics because it affects students' ability to understand what they hear.
What will happen to be if we increase signal-to-noise ratio?
The higher the signal-to-noise ratio, the higher the quality of the signal. Even though SNR is not often used for a digital communication system, but there is a relationship between the system's SNR and BER – the higher the SNR, the lower would be the corresponding BER.
