ABSTRACT:
A vibration monitoring system for aircraft engines includes a nonrecursive digital filter network controlled by a data processor. Digital techniques process tachometer signals to general sampling signals at a frequency which is an integral multiple of the rotating frequency. A novel digital filter can track the rotational frequency of the rotating component and can be accurately centered upon that frequency. The digital filter includes a pair of memories, one of which stores constant coefficients and the other of which stores sampled data. The sampled data storage can accommodate the output of more than one sensor and data from each sensor can be alternatively processed.
