Analog Filters

Aim

The aim of the course is to provide insight into principles and methods for design of analog filters. After the course, the student should be able to:

• Explain basic concepts and principles of analog filters as well as synthesize filters using standard methods.
• Realize and analyze passive filters.
• Realize and analyze active filters.
• Use computer programs to synthesize analog filters and implement passive and active filters using physical components.

Content

The lectures, exercises, and laboratory work cover:

• Filter Synthesis: Basic concepts and principles of analog filters, specifications, standard approximations, frequency transformations.
• Passive filters: Realization and implementation, discrete and distributed components, resistors, inductors, capacitors, unit elements, ladder structures, Richard’s structures, lattice structures, computation of component values, component sensitivity, frequency transformations.
• Active filters: Realization and implementation, discrete components, resistors, capacitors, operational amplifiers, realization of first- and second-order sections, cascade realizations, coupled forms, simulation of passive ladder structures, topologic simulation, immittance simulation, computation of component values, component sensitivity, scaling of signal levels.
