ABSTRACT:
Disclosed is a system for decomposing an original signal of arbitrary frequency content into a user determined plurality of signals, each of which signals is centered about a variable center frequency. The system of the present invention utilizes a Bank of a plurality of combination Phase Lock Loop and associated Band Pass Filter Bank Components, the Center Frequency of a Frequency Pass Band of each of said Band Pass Filters being effected by use of a signal input thereto, and output by, an associated Phase Lock Loop. The present invention system is particularly well suited for application in the compensation of vibrations in a physical system as sensed by sensors located therein to sense feed-forward and/or feed-back vibration signals. The use of "Look-up" tables which provide magnitude and phase modification specifications for use in modifying vibration compensating actuator applied signal frequency and phase in feed-forward and in feed-back vibration compensation systems is disclosed as is the use of both feed-forward and feed-back signals in an automated vibration compensation system.
