Synthesis and Design of Passive Filters

Abstract
The all-pole and rational approximations presented in Chaps. 2, 3 and 4 are used in this chapter for the design of doubly resistively terminated passive ladder filters. In the general case presented in earlier chapters, we have determined for each approximation the corresponding transfer function of the filter from given magnitude specifications. Although this can be done in the case of passive filters, it is preferable to determine the input impedance function, which can then be synthesized as resistively terminated LC ladder circuit. Some particular design limitations concerning even order filters are also addressed in this Chapter. All design methods and procedures are demonstrated through simple but also more complicated design examples.
