The joining of two noncorrelated electric power currents without using frequency-dependent elements
Abstract
The problem of feeding two electric power currents from two noncorrelated transmitters, e.g. audio and video in TV broadcasting on line, e.g. the antenna feedline, with lowest possible losses and without using frequency-dependent elements, is discussed. The necessary absorption and reflection losses, resulting from the energy conservation law, are calculated. The matching and decoupling conditions of the individual ports of the threeport, used for power joining, as a result of the energy conservation law and the reciprocity law, are also calculated. Circuits are indicated, proving the feasibility of applying the conditions resulting from both laws.
