Question: What is the main advantage of using an integrator circuit with an op-amp?

Options:

1. It provides a constant output voltage
2. It can convert a square wave to a triangular wave
3. It amplifies high-frequency signals
4. It filters out low-frequency noise

Correct Answer: It can convert a square wave to a triangular wave

Solution:

An integrator circuit converts a square wave input into a triangular wave output by integrating the input signal over time.
