When a step-input is given to an op-amp integrator, the output will be______________?
Correct answer: A. A ramp
- A. A ramp
- B. A sinusoidal wave
- C. A rectangular wave
- D. A triangular wave with dc bias
Explanation
For an op-amp integrator, the output is proportional to the time integral of the input. Integrating a constant step produces a linearly increasing or decreasing ramp.
