Abstract

516,844. Frequency changing. STANDARD TELEPHONES & CABLES, Ltd. (Western Electric Co., Inc.). July 26, 1938, No. 22220. Addition to 477,875. [Class 38 (ii)] In a frequency changer comprising a saturable core inductance 13 from which are derived groups of 'odd and even harmonics by filter circuits 16, 19 coupled through transformers 15, 18 and utilizing a bridge arrangement of rectifiers 17 to produce the even harmonics as described in the parent Specification, difference in amplitude of the two groups of harmonics due to the impedance of the rectifiers is compensated for by making the two transformers of different ratio. The harmonics may be further developed by the use of shunt condensers 21 in association with the series condenser 20. The amplitude of a particular harmonic may be adjustable by adjustment of the resistance RE of the corresponding filter circuit.
