Abstract
A vibration data processor and processing method uses a frequency domain filter having low pipeline delay and accurate time domain signal reconstruction. The filter may be user configurable, and the filter may receive input data from a variable number of decimation stages. Sequences of extracted vibrational features are routed to a variable length output buffer for event detection.
