Digital Logic Doubt

Question

In the min term we select (1), in the max term we select (0).

But 1 is greater than 0. Selecting 1 should be called max-term and selecting 0 should be called Min-term. Why they have the name otherwise?

hahaha i could not get anything. :P

Answer 1

consider the truth table

A	B	F
0	0	1
0	1	0
1	0	0
1	1	1

Now the minterm representation is F=Σ(0,3)=A'B'+AB

maxterm representation is F=π(1,2)=(A+B')(A'+B)

now see, if AB is true i.e =1 it is enough to F be =1

but for maxterm representation only (a+B') or (A'+B)=1 does not make the function true, all the terms should be = 1 to make the function=1. That is why minterm and maxterm, hope you understood.
