Abstract: A sampled data system for computing the amplitude of a singal received from a vibration sensing probe minus the fundamental frequency associated with the running speed of a rotating machinery shaft. This signal is known as the Not 1X waveform and variations in its amplitude can signal problems with bearings, rotors, cracks or mechanical looseness, and/or fluids of the rotating machine. The amplitude of the Not 1X waveform can be provided in either peak to peak amplitude, peak amplitude, absolute average or root mean square.
