3 cards from this section. Quick, good the night before a test.
What does FFT stand for?
Think about how signals are analyzed.
Name one application of wavelet analysis.
Consider situations with sudden changes.
What is the primary function of the Fast Fourier Transform?
Consider how signals can be viewed in different ways.
True or False: Wavelet analysis is better for analyzing stationary signals.
Think about the characteristics of signals that change over time.
Using FFT, analyze a hypothetical vibration signal from an industrial motor. Identify significant frequency components that indicate potential issues.
Look for abnormal spikes in frequency response charts.
Propose a predictive maintenance plan that uses wavelet analysis to monitor the integrity of a pipeline subject to Dynamic load fluctuations.
Focus on how changes in signal pattern can inform maintenance timing.
