@Mohiyuva it's all about "and gate" & "or gate".


Truth Table:

A -- B -- C -- Output
0 -- 0 -- 0 -- F
0 -- 0 -- 1 -- F
0 -- 1 -- 0 -- F
0 -- 1 -- 1 -- T
1 -- 0 -- 0 -- T
1 -- 0 -- 1 -- T
1 -- 1 -- 0 -- T
1 -- 1 -- 1 -- T.

5 true. So 5 minterm.

If we obtain the minterm then how can we obtain max term?

Please, anyone explain it.
Dhammapriya said:   7 years ago
First of all, we need to convert a given logical expression into the standard form for minterms called canonical form. Ex. A+BC = A(B+B')(C+C') + BC(A+A').

Now solve this expression with the help of Boolean Laws you will arrive at A+BC = ABC + ABC' + AB'C + AB'C' + A'BC.

ABDULLAH AKHTAR said:   8 years ago
Your formula A + BC = (A + B) (A + C). Is write but we have to find minterms @RAMESH.
