An automated climate control system regulates a heater output (QQQ) based on two sensor inputs: a temperature override sensor (TTT) and a manual shutdown switch (SSS). The heater is active (Q=1Q = 1Q=1) only when both the temperature override is inactive (T=0T = 0T=0) and the shutdown switch is inactive (S=0S = 0S=0). This logic corresponds to a NOR gate.
Complete the truth table for this NOR logic gate.
| Input TTT | Input SSS | Output QQQ |
