Q5:
What is SNR and what’s the effect?
A5:
In analog and digital communications, Signal-to-Noise
Ratio, often written SNR, is a measure of signal strength
relative to background noise. The ratio is usually measured
in decibels (dB).
In digital communications, the SNR will probably cause a
reduction in data speed because of frequent errors that
require the source (transmitting) computer or terminal to
resend some packets of data. SNR measures the quality of
a transmission channel over a network channel. The greater
