It's Friday. Do you really feel like working? Well then, take a break and test your knowledge with four questions. Answers appear on the last page. We'll have four more questions for each of the next two Fridays.
The questions originally appeared in Test & Measurement World.
Eye diagrams make it possible to characterize the jitter that is present on serial-bus digital signals. Which of the following statements best describes the relationship of an oscilloscope to an eye diagram?
- The eye diagram is a frequency-domain representation and cannot be displayed by an oscilloscope.
- The eye diagram is a frequency-domain representation that you can obtain by performing a fast Fourier transform (FFT) on data captured by a digital storage oscilloscope.
- An eye diagram is a time-domain overlay of many bit signals.
