A digital safety system monitors two independent sensor inputs, T1 T_1\,T1 and T2T_2T2, and produces control signals C1 C_1\,C1 and C2 C_2\,C2 according to two different logic gate configurations.
Identify the logic gates represented by Truth Table 1 and Truth Table 2.
Truth Table 1:
| Input T1T_1T1 | Input T2T_2T2 | Output C1C_1C1 |
|---|---|---|
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
Logic gate 1: .....
Truth Table 2:
| Input T1T_1T1 | Input T2T_2T2 | Output C2C_2C2 |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
