Question 3: When testing a high-speed digital circuit, what should be prioritized to minimize measurement error?

Which action should you take?

Choose only one option

Ensure that the circuit is powered with stable DC power

Use a low-bandwidth oscilloscope with high time resolution

Use an oscilloscope with high bandwidth and low noise floor

Use a simple voltmeter to check the output

Question 4: What is the purpose of using a fault tree analysis (FTA) in diagnosing complex circuit failures?

Which action should you take?

Choose only one option

To systematically evaluate the logical causes of a failure and identify root causes

To simulate the circuit under various failure conditions

To check the environmental conditions in which the circuit operates

To measure the voltage and current at each component

Question 5: Why is it important to analyze the signal integrity of power rails in high-speed circuits?

Which action should you take?

Choose only one option

To verify the performance of the power supply

To ensure the stability and clean operation of the circuit

Question 6: How does a signal's rise time affect its integrity in high-speed digital systems?

Which action should you take?

Choose only one option

Rise time has no significant impact on signal quality

Slower rise time causes more signal degradation and noise

Rise time only affects analog signals

Faster rise time leads to better signal clarity
