Explanation: The drawback of zero crossing detectors can be in cured with the use of regenerative or positive feedback that causes the output to change faster and eliminate any false output transition due to noise signals at the input. 10. Name the comparator that helps to find unknown input.
A. Time marker generator
B. Zero crossing detectors
C. Phase meter
D. Window detector
Answer:A
