| are not equal to the chatacteristic impedance ofthe used line, it produces signal reflections that causes interferences. It is then necessary the "matching", or "termination", ofthe transmission lines. Parallel termination: The termination method that gives better performances is the "parallel" one. In case of poit-to-point transmissions, in parallel at the receiver it is necessary insert between terminals A and B a resistance with same value of the line characteristic impedance about 120 Ohm. (About this argument refer to the JumperJP3 configuration). |
