5. Simplify the following functions and implement them with two-level NAND gate circuits: a) F(A,B,C,D)=(A' + B'+C) (A' + B') (A' + C) b) F(A,B,C,D)=A'B+A+C+D'

4- Use NAND gate, NOR gate, or combinations of both to implement the following expréssion:- a) X=A [B+C (D+E)] b) X=B (CDE +EF G) (A B+ C)

Q.Simplify the following functions, and implement them with two-level NAND gate circuits: (a) FABC.D) = AC'D' + A'C + ABC + AB'C + A'C'D' (b) F(AB.C.D) = A'B'C'D + CD + AC'D (c) FABC.D) = (A' +C' + D')(A' + C')(C' + D') Handwriting %3D (d) FAB.C.D) = A' + B + D' + B'C %3D

6. A 8 bit ADC has generated a digital representation of 11001100 using the successive approximation method due to an unknown amount of input voltage. If the ADC's designed range of operation is 0-10 V, calculate the possible range of this unknown input voltage. [3]
