Extracted text: How did he get the value inside the circle, can you explain step by step? ratio of SNR value over the absolute maximum value of an analog signal =(Xrms\XImax), We have to determine SNR in terms of m bits. Step 2 of 3:) The signal to quantization noisc power ratio E(x) E(c;) SNR = > Relationship between SNR xrms and step size is defined as Arms SNR = 10.79+20 logo A where x= RMS value of the signal to be quantized x. Xmax A= min 2 %3D L. Substituting A in Equation O SNR = 10.79 + 20- log,0 2|x /2 Imax =10.79 + 20- log,o +20m log, 2- 20 log10 2 Imax =10.79 + 20- log,o 20m (0.3010)- 6.02 SNR = 4.77 + 20 log,ol Xms+6.02m Imax Step 3 of 3:) SNR = 4.77 +20- logo +6.02m Imax
