This book is a unique collection of over 130 tasks and fully worked-out solutions for circuit representation, analysis, and simulation of electromechanical and electroacoustic systems. It complements the textbook "Electromechanical Systems of Microtechnology and Mechatronics" and goes far beyond it with tasks related to piezoelectric accelerometers, bass reflex boxes, condenser microphones, rate sensors, organ pipes, flat coils, magnetostrictive benders, nonlinear microvalves, and a broadband piezoelectric signal generator. Readers can also verify the efficiency of the methods and tools of electrical engineering through online examples available for the free circuit simulator LTSPICE. The book is aimed at students of measurement and automation technology.
