Abstract

486,286. Preventing inductive and other disturbance. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Nov. 20, 1937, No. 32001. Convention date, Nov. 23, 1936. [Class 40 (iv)] [Also in Group XL] An amplifier with negative reaction is inserted between a generator feeding two or more electric circuits and the circuits to reduce cross talk, the negative reaction being adjusted so that the amplifier has a low internal resistance. As shown the generator e feeds the two modulators M1, M2 through the amplifier which is back coupled by means of the potentiometer P. By suitably adjusting P the effective internal resistance of the tube can be reduced to a negligible amount. Resistances R may be provided if desired to reduce still further the coupling between the circuits.
