Sommario/riassunto

Discrete Signals and Inverse Problems examines fundamental concepts necessary to engineers and scientists working with discrete signal processing and inverse problem solving, and places emphasis on the clear understanding of algorithms within the context of application needs. Based on the original 'Introduction to Discrete Signals and Inverse Problems in Civil Engineering', this expanded and enriched version:combines discrete signal processing and inverse problem solving in one bookcovers the most versatile tools that are needed to process engineering and scient
