The Signal-to-Noise Ratio (SNR) calculator computes a relative measure of the strength of the received signal (i.e., the information being transmitted) compared to the noise.
INSTRUCTIONS: Enter the following. SNR = 20 * log10(S/N)
SNR: The calculator returns the SNR in dB.
When signals are a measure of amplitude, in measures such as volts (V) or amperes (A), the formula for Signal to Noise Ratio is:
SNR = 20 * log10(S/N)
