摘要

The invention concerns a circuit arrangement for carrying out impedance matching in connection with transmission lines. The circuit arrangement comprises a control stage 11, a dynamic input impedance consisting of a resistance, and a transformer 13 provided with primary and secondary windings. The control stage 11 and the input impedance are connected to the poles of the secondary winding of the transformer 13 and the transmission lines, which have different characteristic impedances, are connected individually to the poles of the primary winding of the transformer 13. According to the invention the circuit arrangement is characterized by the circuit arrangement for generating a resistive input impedance comprising a processor 15 and a device 14 for carrying out the matching. <IMAGE>
