Memetic Method for Passive Filters Design
Tomasz Golonek, Piotr Jantos · InTech eBooks · 2013
The design of analog passive filters with specialized (not typical) frequency responses is not a trivial problem. The presence of finite load impedances for filter sections and limited qual‐ ity factors of coils are just two of many concerns which a design engineer has to take into account. Additionally, classical techniques of filters synthesis require assuming of the ap‐ proximation type (e.g. Butterworth, Chebyshev) before calculating the filter transfer func‐ tion’s poles and zeroes. This choice is frequently a challenge itself.
