The SHM community is constantly exposed to various aspects of signal processing, spectra collection, data processing and analysis, pattern recognition, and decision-making. This chapter reviews some of these aspects. Both the state-of-the-art and general principles, on one hand, and specific examples, on the other hand, are presented.
