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(x*) E(c;) SNR = 20?? > Relationship between SNR, xrmsd step size is defined as SNR =10.79+ 20-log,d where x = RMS value of the signal to be quanthred x. A= min 2 > Substituting A in Equation D Xms SNR =10.79+ 20 · logjo /2" =10.79 + 20- log,o + 20mlog,, 2- 20 log10 2 Imax =10.79 + 20 - log,o +20m (0.3010)- 6.02 max SNR = 4.77 + 20- log,o X pms+6.02m Imax Step 3 of 3:) SNR = 4.77 +20- log10 +6.02m Imax
