WebAug 6, 2024 · SNR (dB) = 20*Log(S/N) Note that since the signal and noise values are represented as voltage levels, there’s a square or 20*log relationship to convert to power ratio. Example Calculations If the signal and noise voltage levels are the same, the SNR is 0 dB. For a signal level of 9V and Noise level of 3V, the SNR is 9.54 dB. Can SNR be negative? WebThe other method is when you know the NR value that must be achieved.

Z-weighting is a flat frequency response of 10Hz to 20kHz ±1.5dB. This response replaces the older "Linear" or "Unweighted" responses as these did not define the frequency range over which the meter would be linear. Z-weighted measurements are expressed as dBZ or dB (Z).
