How does SNR affect the measurement of a signal?

In the most basic terms, SNR determines how usable your signal will be. A higher SNR value means the signal is clearer. With a lower value, you start to introduce Gaussian noise into your network (expressed as static), and as the number becomes closer to 1, the worse the static gets.

How do you measure SNR?

Furthermore, for power, SNR = 20 log (S ÷ N) and for voltage, SNR = 10 log (S ÷ N). Also, the resulting calculation is the SNR in decibels. For example, your measured noise value (N) is 2 microvolts, and your signal (S) is 300 millivolts.

Does SNR increase with distance?

External Antennas Improve SNR Through Proximity

If traveling through air, radio signals lose amplitude (signal strength) in accordance with the inverse square law; if the distance between a transmitter is doubled, the amplitude of the signal seen by the receiver will be four times less strong.
