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

Question

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:

Please help would be appreciated.

Answer 1

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.

Answer 2

The solution is to apply Kmap. We will be ending up with an equation that will be similar to

but this is not the reduced form. If we try to reduce this equation we will end up with 1.
