Multiplexer Circuit Output
A 8x1 MUX is used to realize a four variable function, F(A,B,C,D) = Sigma M(0,2,4,6,7,9,14,15). A is LSB which is the input to the MUX. In select lines B is the MSB and D is the LSB THEN input to the MUX From Io to i7 is : A. A' A A' 0 A 0 1 1 B. A A A' 0 A 0 1 1 C. A' A' A 0 A 0 1 1 D. A' A A' 0 A' 0 1 1

Sum of Product and Product of Sum
I have a doubt it may be stupid though. know that if ∑m (1,3,5,6) then its equivalent POS form is = πM (0,2,4,7) But my doubt is say i need to represent 7, in SOP i write ABC in POS i write (A'+B'+C') ∑m (1,3,5,6) = A'B'C + A'BC+AB' ... then why we say that SOP is complement of POS and why ∑m (1,3,5,6) != πM(1,3,5,6) ? as according to above they seems to be equal.
