Course detail
Electronic Filters
FEKT-BPA-ELFAcad. year: 2022/2023
Analog filters are still inseparable parts of complex electronic devices. Thus, its analysis and design process belongs to the basic application-oriented bachelor capabilities. This course covers passive and active filtering structures with traditional and unconventional functional blocks (synthetic inductors, elements known as FDNR, super-niductors), filters which utilize special physical principles (SAW, crystal filters) as well as filters based on switching mechanism (switched capacitors). From the viewpoint of practical applications we are speaking about electronic systems with accumulation elelemts which are able to process signals with frequencies up to 100MHz in real time. In computer exercises students learn how to solve problems of computer-aided analysis and design of the typical filter topologies by using available software (Orcad Pspice, Snap, NAF, Matlab, Mathcad) including filter optimization from different aspects.
