Industrial safety and environmental control systems utilize logical decision-making to operate machinery.
In a chemical processing plant, a ventilation extraction fan is activated (F=1F = 1F=1) when the toxic gas concentration is high (G=1G = 1G=1) AND the maintenance shutdown switch is NOT active (M=0M = 0M=0).
This control logic can be represented by the expression: G AND (NOT M)G \text{ AND } (\text{NOT } M)G AND (NOT M).
Complete the truth table for this system.
| G | M | G AND (NOT M) |
|---|---|---|
| 0 | 0 | |
| 0 | 1 | |
| 1 | 0 | |
| 1 | 1 |
