Signal Integrity — question 9 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
You have two parallel traces running side by side for several inches: an aggressor carrying a fast clock, and a victim carrying a data signal that occasionally gets corrupted. On the scope, you see two different kinds of unwanted bumps: a narrow pulse on the victim near the driver end that appears right at the aggressor's edge, and a wider, bipolar-looking pulse on the victim near the far/receiver end. Explain what's causing each of these, why they look different, and how you'd reduce the coupling.
