Sensors & Data Acquisition — question 7 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 an accelerometer and a gyroscope you want to combine to estimate tilt angle. The accelerometer is accurate over long timescales but noisy instantaneously; the gyroscope is smooth and accurate instantaneously but drifts over time. How would you combine them, and what does the crossover frequency of your fusion filter actually represent?
