And how did he get the value inside the circle, and is it true or false? 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 = > Relationship between SNR, xrms and step size is defined as SNR = 10.79 + 20- logo where x= RMS value of the signal to be quantized x.
