Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are tasked with diagnosing a structural issue in a bridge. Explain how you would use cross-spectral analysis to assess vibrations recorded by multiple sensors.

💡 Hint: Consider the relationship between collected data points from different sensors.

Challenge 2 Hard

Two machines generate vibrations measured by sensors. One shows a high coherence value between the inputs, while the other shows a low coherence. Analyze the possible implications for machinery diagnostics.

💡 Hint: Focus on what coherence tells us about the signals' behaviors in each scenario.
