Abstract: This paper presents the bases of a test method that can detect and locate faults and defects. This method is based on the use of digital signal processing applied on sampled current or voltage and can be applied to technologies with significant quiescent current. A simple procedure is also proposed in order to locate parasitic resistive contacts, and diagnosis potential of the method is explored.
