In the resistive DC bridge the feed current of the signal processing circuit and the signal voltage are balanced, and the resultant AC and modulated DC are transmitted together to produce separate U.I products in an impedance. The balancing operation for the feed current of the signal processing circuit is effected by two paired voltage dividers. - Two copies of the signals, time-delayed in relation to one another are mixed and fed to the impedance. The modulated DC, after passage through the reproduction impedance, is recollected in an inverting counterposed pole inthe form of a half-period rectifier activated by mother signals with a ripple current of its wave speed. The half-period rectifier, in common with the bridge, establishes the local signal direct current. |
