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 noise power ratio E(r*) E(c;) SNR = > Relationship between SNR, xrms and step size is defined as SNR = 10.79 + 20 - logo A where x = RMS value of the signal to be quantized x. 21 -Xmi Imax A=max > Substituting A in Equation D Xms SNR =10.79 + 20 - log0 2|x /2" Imax =10.79 + 20- log,0 ms+ 20m log, 2- 20 log1o 2 =10.79 + 20 - log10 d 20m (0.3010)- 6.02 SNR = 4.77 +20- logp +6.02m Imax Step 3 of 3:) SNR. = 4.77 + 20- log, +6.02m
