1,125,459. Modulators; stereophonic radio receivers. TESLA, NARODNI PODNIK. 2 May, 1966 [6 May, 1965], No. 19199/66. Heading H3R and H4L. The modulator/demodulator described in Specification 1,105, 632, is modified in that each arm of the bridge includes a reactance. In one arrangement, Fig. 2 (not shown), each arm comprises two capacitors, the diodes being connected to the junctions of pairs of capacitors and the mid-points of adjacent arms of the bridge being joined by resistances to provide D.C. paths for the diodes. In another arrangement, Fig. 3 (not shown) each arm comprises a capacitor and a resistance.
