PCA application to frequency reduction for fault diagnosis in analog and mixed electronic circuit
Damian E. Grzechca, Jerzy Rutkowski, Tomasz Golonek · 2010
This paper is focused on the diagnosis of analog and mixed electronic circuit in frequency domain. A multi tone signal excites a circuit under test in order to detect and locate a single fault. The input signal consists of a number of frequencies which are selected by Principal Component Analysis (PCA) algorithm. An exemplary circuit has been examined and results have been discussed.
