Abstract

453,847. Impedance networks. MERDLER, L. R., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. March 18, 1935, No. 8355. [Class 40 (iii)] A band filter for use in wireless television receiving apparatus or the like comprises three tuned circuits 1, 2, 3, coupled together variably or otherwise and tuned respectively to the cut-off and middle frequencies of the pass band. Damping may be introduced by means of the shunt resistances 7, 8, 9.
