Final answer:
Without access to Figure 3.35, it's not possible to provide a correct truth table or logical operation for Z in terms of A and B from the transistor-level circuit. The transistor behavior needs to be analyzed in the context of the given logic gate operations to determine the correct answer.
Step-by-step explanation:
The student seems to be referring to a transistor-level circuit and attempting to determine the logical operation performed by the circuit, represented by the variable Z in terms of A and B. Without a visual reference to Figure 3.35, it is impossible to accurately deduce the truth table or the logical operation. However, if the options provided a) Z = A AND B, b) Z = A OR B, c) Z = A XOR B, and d) Z = NOT A are all the possible operations the circuit could be performing, the student would need to analyze the specific structure and behavior of the transistors in the circuit to identify which one is correct. For example, the truth table for each operation is distinct:
- For an AND gate, Z is true only if both A and B are true.
- For an OR gate, Z is true if either A or B is true.
- For an XOR gate, Z is true only if A and B are different.
- For a NOT gate, Z is the inverse of A, and B is not relevant.
Once the behavior of the transistors is understood in relation to these operations, the correct truth table and logical operation can be identified for the circuit in question.
