Abstract
A device for stereophonic reproduction of signals supplied in the form of the sum signal A + B of the coherent stereophonic signals A and B and of the difference signal AB of said coherent stereo signals, which modulate in amplitude a subcarrier frequency with suppression of the carrier, in common with a pilot signal of half the carrier frequency, to the device comprising at the input end the parallel combination of an information channel, which passes the incoming stereo signals and a pilot channel passing only the signal pilot, comprising a frequency doubler for the local production of the carrier frequency, the information channel and the pilot channel being connected, in order to restore stereophonic signals A and B to diagonal points of a ring comprising on each branch the combination series of a resistor and a rectifier, the rectifiers having the same direction of passage in the course of the ring, while the coherent signals A and B are derived from output resistors connected to the other diagonal points of the ring, characterized in that the union of the series resistor and the rectifier in a branch of the ring and the corresponding union in the opposite branch of the ring are each connected, through a separate resistor to the terminal of the bias voltage source, and because the other terminal of the bias voltage source is connected through the two output resistors forming connections that continuous currents pass to the diagonal points of the ring connected to said output resistors, said polarization voltage source providing an identical pre-setting of all the ring rectifiers in the direction of passage.
