This is also the case for digital and switched-capacitor filters.The reader is strongly recommended to carefully study the principle of maximum power transfer, sensitivity to element errors, and the implications of Equation (3.26).

The author also includes a wealth of solved examples as well as end of chapter problems for both students and instructors. Other topics covered are basic circuit elements and their descriptions, first- and second-order sections using single and multiple amplifiers, coupled forms and signal scaling, and various methods for immitance simulation among others.Īnalog Filters Using MATLAB can be used both at the undergraduate and graduate levels as well as for industrial designs. Discussions of passive LC filters with lumped elements and passive filters with distributed elements are also included. The author includes many topics such as filter technologies, terminology, and basic concepts, common frequency-selective filters, and advanced approximations. A supplementary toolbox in MATLAB is employed in order to minimize the need for advanced mathematics. The material covers the synthesis and design of classical passive filters with both lumped and distributed circuit elements, and active filters based on operational amplifiers, transconductors, and current conveyors.
Analog Filters Using MATLAB provides a comprehensive overview of the theory and modern design methods for frequency-selective analog filters as well as describing how to select and design analog filters using MATLAB.
