Question 1: What is the role of an oscilloscope in fault diagnosis of a high-speed digital circuit?

Which action should you take?

Choose only one option

To capture signal waveforms and identify timing issues or noise

To measure current flow in a component

To test the operating temperature of the circuit

To measure resistance and continuity in the circuit

Question 2: In testing an analog-to-digital converter (ADC), what is the most important characteristic to check for accuracy?

Which action should you take?

Choose only one option

Frequency response of the input signal

Signal-to-noise ratio (SNR) and linearity

Digital output timing precision

Output voltage swing range

Question 3: What is the effect of increasing the rise time of a signal on its integrity?

Which action should you take?

Choose only one option

It reduces the chance of signal reflections

It increases signal distortion

It improves signal clarity

It decreases signal attenuation

Question 4: When diagnosing a fault in a low-power system, what is the most likely cause of malfunction?

Which action should you take?

Choose only one option

Power supply instability or insufficient current

Faulty signal routing

Incorrect software configuration

Component overheat

Question 5: In an analog circuit, what is the most likely cause of a "pop" noise during power-up?

Which action should you take?

Choose only one option

Inductor saturation during power-up

High-frequency oscillation due to feedback loop

Incorrect grounding causing transient voltage spikes

Capacitor inrush current

Question 6: How can you ensure that the test plan will provide reliable results in the presence of noise in an electronic circuit?

Which action should you take?

Choose only one option

Ignore noise, assuming it will not affect the test outcomes

Increase the input signal strength to overpower the noise

Use only digital signals for testing

Incorporate noise immunity and filtering into the test setup
