Hi again-
Here are the instructions to the second problem that I am wondering about:
A combinational circuit is specified by the following Boolean function:
F(A,B,C,D)= Ʃ(0,2,6,7,8)
Implement the circuit using ONE 4:1 multiplexer and other necessary gates. Use A and B as MUX selection inputs. Only uncomplemented inputs are available.
My attempt at a solution is as follows:
A B C D F
0 0 0 0 1
0 0 0 1 0
0 0 1 0 1
0 0 1 1 0
0 1 0 0 0
0 1 0 1 0
0 1 1 0 1
0 1 1 1 1
1 0 0 0 1
1 0 0 1 0
1 0 1 0 0
1 0 1 1 0
1 1 0 0 0
1 1 0 1 0
1 1 1 0 0
1 1 1 1 0
Above is my truth table. The problem should be fairly simple only I am confused of how to set it up with the directions saying I should only use uncomplemented inputs. That is because I got D0 = D' and D2= C'D'. How should I procede to get the correct answer? Thanks in advance for your help!
