How to Calculate the Signal to Noise Ratio
The signal-to-noise ratio (SNR) provides a comparison of the amount of signal with the amount of background noise in a particular signal, such that a higher SNR indicates the background noise is less noticeable. The SNR is used extensively ... Read More »

How to Increase a Cable Modem Signal to Noise Ratio
Signal-to-noise ratio (SNR) is a gauge of signal strength to and from your cable modem in relation to the background noise. The ideal SNR range is 30 to 50 decibels (dB). High noise or low power levels reduce the SNR and can negatively affe... Read More »
