In an op-amp differentiator:________________?
Correct answer: A. the amplitude of output is proportional to rate of change of input
- A. the amplitude of output is proportional to rate of change of input
- B. the amplitude of output is proportional to input
- C. output occurs when input is finite and constant
- D. polarity of input and output is the same
Explanation
An op-amp differentiator produces an output proportional to the time derivative of the input, so faster input changes produce a larger output amplitude. Its output polarity is normally inverted, which rules out option d.
