A Systematic Designing Approach for Signal-based Fault Diagnosis System, Part 1

This paper deals with the design methodology of fault diagnosis systems based on signal analysis. Fault diagnosis systems generaly have to be engineered individualy, therefore it is of interest to develop tools and schematic design process as aimed in this paper, which reduce the engineering expense...
