Which of the following is NOT true for Schmitt Trigger ?
- A. Schmitt trigger can be used as Sine-to-Square Wave converter
- B. Schmitt trigger uses OP-AMP in Open Loop Mode.
- C. Hysteresis exists in Schmit Trigger
- D. None of the above
Answer: B. Schmitt trigger uses OP-AMP in Open Loop Mode.
Explanation: A Schmitt trigger operates using positive feedback, meaning it uses an Op-Amp in a closed-loop mode, not open-loop. Therefore, statement (b) is incorrect. It does exhibit hysteresis and can be used to convert a sine wave into a square wave.
