Consider a 4-bit digital word D=b3b2b1b0 (see Eq. 1.3) used to represent an analog signal vA that varies between 0 V and +15 V.
(a) Give D corresponding to vA=0 V,1 V,2 V, and 15 V.
(b) What change in vA causes a change from 0 to 1 in (i) b0,(ii) b1,(iii) b2, and (iv) b3?
(c) If vA=5.2 V, what do you expect D to be? What is the resulting error in representation?
