Stable fan filter design using two-variable reactance functions
Abstract
Two-variable reactance transformation (as proposed by King et al., 1982) for the design of stable two-dimensional recursive fan filters with narrow stopbands is compared with the design method proposed by Bruton et al. (1981) using numerical optimization of a resistively terminated (2 + n sub 1 + n sub 2)-port network. The method of King et al. is found to be definitely more simple to design.
