🔍 Key Concepts

• Compare the truth table in panel A with standard logic gate truth tables (OR, XOR, NOT, NOR). • Notice when the output is 1 versus when it is 0, and how that relates to the inputs A and B. • Look at the PLC ladder diagram in panel C and the timing diagram in panel D to confirm how the output behaves when both inputs are on together.

💭 Think About

• For which type of gate is the output ON only when exactly one of the two inputs is ON, but OFF when both are OFF or both are ON? • Which of the listed gates gives an output of 0 when both inputs are the same (both 0 or both 1)? • From the relay/ladder diagrams, what happens to the output path when both A and B contacts are energized at the same time?

✅ Before You Answer

• Verify the line in the truth table where A = 1 and B = 1 and note whether the output is 0 or 1. • Check whether the gate type you choose would ever give an output of 1 when both inputs are 0 (compare with the table). • Confirm that your chosen gate type matches all four input combinations shown, not just one or two of them.
