Q1:

Which of the following Boolean Expression correctly represents the relation between P, Q, R and M1?

A M1 = (P OR Q) XOR R

B M1 = (P AND Q) XOR R

C M1 = (P NOR Q) XOR R

D M1 = (P XOR Q) XOR R

ANS:D - M1 = (P XOR Q) XOR R

M1 = Z XOR R M1 = (X, Y) XOR R = M1 = [P.Q.(P + Q)]XOR R = (PQ + PQ) XOR R = (P XOR Q) XOR R.
