Mathematics for Understanding Waveform Relationships
March 18, 2019
FFT and PSD mathematics are powerful tools for analyzing the characteristics of a given waveform. To learn about the FFT and PSD, see the VRU course Random Testing.
This course focuses on other types of mathematics that are used to understand the relationships between two or more waveforms. Each section below presents the mathematical basis of a specific, commonly used function.
To learn how the transfer function, coherence and cross spectral density are implemented in VibrationVIEW, see the VRU course VibrationVIEW Analyzer Software Package.
