Challenge Problems
Push your limits with advanced challenges
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.
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.
