If the input to a differentiating circuit is a saw-tooth wave, then output will be _____________?
Correct answer: D. Rectangular
- A. Square
- B. Triangular
- C. Sine
- D. Rectangular
Explanation
The ramp portion of a sawtooth has an approximately constant slope, so differentiation gives a constant level; the rapid reset gives a sharp pulse. Together these form a rectangular waveform, rather than a triangular or sinusoidal one.
