Abstract
A system for determining the phase displacement of vibration data signals relative to tachometer point signals by synthesizing a sine wave signal having the amplitude of the vibration data signals, shifting the phase of the synthesized sine wave signal to null out the vibration data signals and determining the phase and amplitude of the synthesized sine wave signal relative to the tachometer point signals.
