Abstract

PURPOSE:To ensure the connection between more than unit of the signal with no loss and interference for the coupling circuit which connects the signals of plural number of the route with no mutual interference by inserting different impedance into the connecting route. CONSTITUTION:Impedance element 7 and 8 composed of inductance L1 and L2 plus capacity C1 and C2 are provided independently from each other to input terminal (a) and (b) which supply input signal f1 and f2 to secure the connection to output terminal C via element 7 and 8. And the connection between f1 and f2 is carried out simultaneously at terminal C. Capacity C1 and C2 plus inductance L1 and L2 are selected for element 7 and 8 according to the frequencies of signal f1 and f2, thus reducing the loss and the mutual interference of the input signals.
