TWO WIRE DELIVERY SYSTEM OF IMPEDANCE MATCHING TYPE ADDING ROUTING COMPENSATION CIRCUIT

摘要

PURPOSE:To simplify the constitution of balanced circuit network and to make easy for the adjustment, by compensating the impedance mismatching between the balanced circuit network other than DC component and the line with the routing compensation circuit. CONSTITUTION:The DC impedance viewing the line 7 from the hybrid circuit 3 is matched with the variable resistor 10 and the impedance mismatching between the balanced circuit network other than DC component and the 7 is compensated with the routing compensating circuit 9. Thus, the constitution of the balanced circuit network is simplified and the adjustment can be made easy.
