The output state of a logic gate is determined by the input states compared to a set rule. Logic gates operate based on specific logical functions, which define how the inputs interact to produce an output. For instance, in an AND gate, the output is high (1) only when all inputs are high (1); in an OR gate, the output is high (1) if at least one of the inputs is high (1). These defined rules such as AND, OR, NOT, etc., dictate the behavior of the logic gate and ensure a predictable output based on the given inputs.
While factors such as manufacturer specifications might influence the performance and limitations of a gate, they do not directly determine the logic of how inputs relate to outputs. The physical design of the gate and environmental conditions like temperature may affect performance or cause failures, but they do not inherently define how the logic gate operates in terms of input-output relationships. Therefore, the set rules associated with the input states are crucial for understanding how logic gates function, highlighting why this is the definitive factor in determining the output state.
