🔍 Key Concepts
• Digital logic functions and how inputs relate to outputs
• The purpose of a truth table in describing a logic gate or digital circuit
• Difference between a logic symbol/diagram and a table of values
💭 Think About
• Ask yourself: Does a truth table show pictures/symbols, or does it show combinations of input values and the resulting output?
• Consider what you would need if you wanted to fully describe how a logic gate (like AND, OR, NOT) behaves for every possible input.
• Which option talks about all possible input conditions and what the device does for each one, rather than just high or low states of an op-amp?
✅ Before You Answer
• Identify which choices talk about all possible input combinations and their resulting outputs.
• Check whether the option you pick is about logic gates/digital devices in general, not just op-amps.
• Eliminate any choice that focuses only on high or low states without listing all input-output combinations.
