<P>PROBLEM TO BE SOLVED: To make impedances in both modes match with each other, when connecting differential wires having different impedances in a differential mode and a common mode. <P>SOLUTION: In an electric circuit related to an embodiment of this invention, a first differential wire having two wires for transmitting a differential signal outputted from a transmission circuit, and a second differential wire having two wires for transmitting the difference signal to a receiving circuit and an differential mode impedance and a common mode impedance which are smaller than the first differential wire are connected. The electric circuit is equipped with a connecting portion in which a resistor is disposed so as to make the differential mode impedance and the common mode impedance of the first differential wire and the second differential wire match with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
