Signal processing and linear systems by B.P.Lathi
This text presents a comprehensive treatment of signal processing and linear systems suitable for young people and retirees in the field of electrical engineering. Based on the widely published book Linear Systems and Signals by B. P. Lathi, this book offers additional applications for communication, control and filtering, as well as new chapters on analog and digital filters and digital signal processing. Lati emphasizes the physical evaluation of concepts, not just the mathematical manipulation of symbols. Avoiding the tendency to treat engineering as a branch of applied mathematics, he used mathematics to improve his understanding of physical and intuitive concepts rather than simply using it to prove axiomatic theories. Theoretical results are supported by carefully selected examples and analogies that allow students to intuitively find meaning for themselves.
