Abstract

732,273. Filters. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 25, 1953 [Jan. 30, 1953], No. 2788/53. Class 40 (8). A coaxial lattice filter comprises an outer tube OT, an inner tube IT, an innermost tube IIT, and a tube 3T which is branched to form parts FT and 2T connected to IIT and IT, respectively. Short lengths of tube 4T, ST are arranged concentrically in holes H1, H2 to provide admittances. Matrices are given, involving these admittances for the values of the input and output currents and voltages.
