Abstract
725,326. Multiplex radio signalling. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 27, 1953 [March 4, 1952], No. 5536/53. Class 40 (5). In a television receiver, the I.F. vision and sound carriers axe applied from coil 1 to the demodulator 2, 3, 4, the sound signal being derived from the modulated beat oscillation produced between the two carriers. The demodulator output is fed through an inductance 5 to the grid 6 of an amplifier valve 7, or plurality of valves, the input capacity 8 of which forms, with inductance 5, a circuit tuned to the beat oscillation.
