Time Frequency Analysis

nCode GlyphWorks is a powerful data processing system for engineering test data analysis. Unique capabilities include the analysis of signals in Time or Frequency domains. Time domain is traditionally preferred for transient signals whereas frequency domain is typically applicable to steady state processes. Joint Time Frequency analysis is a way to combine both the time domain and frequency domain information into one plot, referred to as a spectrogram or waterfall. This presentation will cover several applications of Time Frequency analysis, mostly related to rotating machinery.
