3 cards from this section. Quick, good the night before a test.
What does FFT stand for in signal processing?
Think of frequency analysis.
Name one advantage of the Wavelet Transform.
Remember that it helps detect changes at different scales.
What is the primary purpose of signal processing in SHM?
Think about how we interpret sensor information.
True or False: Wavelet Transform allows for multi-resolution analysis.
Consider its ability to adjust analysis depending on signal characteristics.
Design an automated SHM system that uses both FFT and neural networks. Outline its key components and workflow.
Think of the flow of data from collection to alert generation.
Provide a detailed explanation of the differences between FFT and Wavelet Transform with practical examples.
Use concrete examples, such as how each method would reveal different information about vibration data.
