Abstract
Following a brief review of previous work on bandstop filters, the inadequacy
of a recent work to obtain a perfect notch or perfect absorption at the notch
frequency ?0 is demonstrated. A simple and elegant alternative solution,
based on purely analytical arguments, is then presented. The resulting
network is shown to achieve perfect matching as well as perfect absorption at
the notch frequency and has several other advantages. A comparison has also
been made with the conventional bridged-T band-stop filter.
