Signal-to-noise ratio is typically expressed as a ratio in dB. Use this calculator to convert from
- dB to linear voltage
- dB to linear power
Signal and Noise Voltage units can be volt, millivolt, microvolt or nanovolt
Signal and Noise Power units can be watt, milliwatt, microwatt, nanowatt
Note that the result of this calculation is a ratio and as such has no units.
SNRlinear volt = 10^(SNRdB/20)
SNRlinear power = 10^(SNRdB/10)
