Concept:

The given circuit is an op-amp differentiator. For an ideal differentiator with input , the output is given by:

Given that , the equation simplifies to:

Given:

The input signal is a triangular waveform.

  • During the rising edge (slope = +1):
  • During the falling edge (slope = –1):

Thus, the output waveform will be a square wave alternating between +1 and –1, switching at every point where the slope of changes.

Answer:

Option 2: Square wave output alternating between +1 and –1 (in response to triangular wave input)
