Exam-style question
Try this first
EC31: For Digital signal processing, a student is analysing a op-amp inverting amplifier. Which option gives the best Combinational logic reasoning for the objective "Use Boolean expressions for simple circuits"?.
- A.EC31 correct: In the op-amp inverting amplifier, the answer follows the signal path from input condition to component response to output change, so it supports Use Boolean expressions for simple circuits.
- B.EC31 distractor: It names a component but does not connect the input condition to the measured output in Combinational logic.
- C.EC31 distractor: It reverses the cause-and-effect chain, so the output is explained before the circuit condition is set.
- D.EC31 distractor: It gives a generic electronics definition without applying the op-amp inverting amplifier context.
Model answer
What a good answer should say
- The correct option is EC31 correct: In the op-amp inverting amplifier, the answer follows the signal path from input condition to component response to output change, so it supports Use Boolean expressions for simple circuits.
Explanation
Why this works
It is best because it keeps Combinational logic anchored to the circuit signal path: input condition, component response, then output change. The distractors are wrong because they omit the output link, reverse the electronics causality, or drift into a generic component definition rather than applying the op-amp inverting amplifier.
