Analog Electronics
42.

Assertion (A): The circuit in figure produces repetitive narrow pulses when input is fed with sine or triangular waveform having peak value more than + V

Reason (R): The high gain op-amp produces voltages at two levels. If input is more than + V, the output is + 15 V otherwise the output is - 15 V.

Both A and R are correct and R is correct explanation for A
Both A and R are correct but R is not correct explanation for A
A is correct R is wrong
A is wrong R is correct
Answer: Option
Explanation:

If input is large the voltage o/p should be -15V and vice versa for a comparator.

If i/p is more o/p should be -15 V otherwise o/p should be +15 V.
