Abstract
The specification describes a system for analyzing and processing an input analog signal. This invention provides an analog signal preprocessor which is operated in conjunction with a main instrument for measuring any defects or wear of machinery parts. The analog signal preprocessor operates to preprocess an analog signal by filtering and amplifying a signal from the analog signal to allow a more accurate reading by the main instrument. The preprocessor will adjust itself for optimum operation and communicate the operation modes to the main instrument. Also, the preprocessor can be addressed by the main instrument to setup the operation of the preprocessor according to a program or input entered into the main instrument.
