Difficulty :

Hard

Explanation

This question assesses your problem-solving skills and ability to troubleshoot complex electronic circuits. Recruiters are looking for candidates who can use systematic debugging techniques, tools like oscilloscopes, and logical thinking. A strong answer will include examples of breaking down the circuit into smaller subsystems and addressing faults. Avoid failing to mention the importance of documentation and testing.

Answer Example

I approach debugging by isolating each subsystem and testing them individually using tools like oscilloscopes and multimeters. For instance, in a recent project, I identified a voltage drop issue in a power supply circuit by measuring node voltages and isolating the faulty capacitor. I documented the steps and ensured proper testing after replacing the component, resolving the issue efficiently. This systematic method ensures accurate fault identification and resolution.
