<Dd> S Q N R d B = P x ν + 6 ν + 4.8 (\ displaystyle \ mathrm (SQNR) _ (dB) = P_ (x ^ (\ nu)) + 6 \ nu + 4.8) </Dd> <P> where ν (\ displaystyle \ nu) is the number of bits in a quantized sample, and P x ν (\ displaystyle P_ (x ^ (\ nu))) is the signal power calculated above . Note that for each bit added to a sample, the SQNR goes up by approximately 6dB (20 × l o g 10 (2) (\ displaystyle 20 \ times log_ (10) (2))). </P>

What is the effect of signal to quantization ratio in data communication
