How to create a circuit that outputs only 1, regardless of inputs

So this is the truth table:

In_1  In_2  In_3  Out
0      0    0      1
0      0    1      1
0      1    0      1
0      1    1      1
1      0    0      1
1      0    1      1
1      1    0      1
1      1    1      1

How do I create a circuit that matches this truth table?

Here is what I have tried, but this did not work: attempt

Please help would be appreciated.

Solution

  • You just need to connect the output to a constant logic 1, which is usually just the power supply voltage. This is a trivial logic function and requires no gates to implement.
