Abstract:
A method for designing an electrical filter for filtering microwaves, the transfer function of which satisfies the following relationship: ##EQU11## G.sub.m (P) being a polynomial function of degree n, called an electrical filter generating function, wherein p is the complex frequency, and h is a predetermined scaling factor, comprising the steps of:a) selecting at least one determined function called a seed function wherein said seed function is a generalized Chebycheff function satisfying the following relationship: ##EQU12## wherein P1 stands for said filtering transmission zeroes; b) determining according to a multiplying step the product of all said seed functions to define said electrical filter generating function G.sub.m (P) and said transfer function;c) translating said electric filter transfer function into transmission zeroes and poles; andd) determining those physical parameters of said electrical filter that achieve said zeroes and poles and utilizing said physical parameters for construction of said electrical filter for filtering microwaves, such that construction is made possible in one single run.
