6.12 a. A total of 28 quantization levels are possible, so the normalized step size is 2 –8
b. The actual step size, in volts, is:
0.003906 × 10V = 0.03906V
c. The maximum normalized quantized voltage is 1 - 2-8 = 0.9961. Thus the actual
maximum quantized voltage is:
0.9961 × 10V = 9.961V
d. The normalized step size is 2–8. The maximum error that can occur is one-half
the step size. Therefore, the normalized resolution is:
+ 1/2 × 2 –8 = 0.001953
e. The actual resolution is
+ 0.001953 × 10V = + 0.01953V
f. The percentage resolution is
+ 0.001953 × 100% = + 0.1953 % -25- ...
