ORDERS V TIME - COMPARING OVERALL LEVELS
By Dr Colin Mercer, Technical Director, Prosig
By combining a speed signal with a data signal and using the Short Time FFT algorithm (Hopping FFT), it is possible to extract order data directly as a function of time (Orders from Hopping FFT) rather than as a function of speed (Waterfall). This is very useful when analyzing a complete operational cycle which includes run ups, rundowns and periods at operational speeds. read »»»
