9.7. Measurement and Analysis Techniques

Try these first

1. 1.

   What is the primary function of an oscilloscope?

   Hint

   Think about how you would observe a waveform.

2. 2.

   What does FFT stand for?

   Hint

   Recall the importance of frequency analysis.

3. 3.

   What does an oscilloscope measure?

   • Voltage over time
   • Frequency content
   • Signal power

   Hint

   Think about its primary function.

4. 4.

   True or False: FFT analysis can only be applied in offline settings.

   • True
   • False

   Hint

   Consider the processing speed of devices.

5. 5.

   You are tasked with designing a PCB for an audio application. How would you utilize both oscilloscope and spectrum analyzer in your testing phase? Discuss the steps.

   Hint

   Consider the order of measurements and their purposes.

6. 6.

   A mixed signal board is failing EMI compliance during pre-testing. What simulation methods would you suggest employing to predict and address potential noise issues?

   Hint

   Think about design changes as potential solutions.
