Abstract
The paper presents an approach of the fuzzy logic expert system to test a specification of voltage controlled oscillator. The expert system takes into account parametric faults and the test procedure is orientated on circuits’ specification. The introduction is focused on analog fault testing, its technics, approaches and goals. Next, the specification parameters are introduced and fault models are clarified. The method uses linguistic variables in the premise section of the expert system. Such variables are described by membership functions that allows to convert linguistic information into numeric values. Then, the conclusion section for the expert system with the Takagi-Sugeno type has been described in details. The approach has been compared with classic dictionary based on SVM method. Finally, the results prove high efficiency of the test specification of VCO circuits.
