How it works
Inputs a and b are fed into AND, NAND, and OR gates. The selected logic result is routed to the output through the control logic. The output state is shown on the connected display.
How to test
Set the inputs and verify the outputs match the table below:
| input a | input b | AND | NAND | OR |
|---|---|---|---|---|
| 0 | 0 | 0 | 1 | 0 |
| 0 | 1 | 0 | 1 | 1 |
| 1 | 0 | 0 | 1 | 1 |
| 1 | 1 | 1 | 0 | 1 |
