A suitable Cauer reactance function is taken as the starting point of an approximation process for the required impedance function. Realizability and convergence criteria of the synthesis are also discussed. A program for LP functions up to order 7 has been developed for use in the HP 9020 desk calculator.decircuit cadlinear network analysislow-pass filterspassive filtersimpedance transferrossy rlc networkselement lossesapproximation processimpedance functionconvergence criteriaHP 9020 desk calculatorfifth order low pass filterdesign procedureimpedance matching621004journal article
