PURPOSE:To equalize the lengths of transfer paths of all signals, and to prevent the generation of attenuation difference and phase difference of the signals by extending each input signal line and each output signal line by prescribed length, respectively. CONSTITUTION:In the matrix switching circuit 10, an interval LA between adjacent intersection parts on each input line A'-H' and each output line a'-h' is set to one unit, and while increasing one unit each in order of arrangement from each intersection part of the end existing on the same side of the input line, each input line is extended, and also, while increasing one unit lh each in order of arrangement from each intersection part of the end existing on the same side of each output line, each output line is extended. That is, the input signal lines A'-H' are constituted by adding an extended part L to each input signal line of each input signal line of a conventional matrix switching circuit, and the output signal lines a'-h' are constituted by adding an extended part l to each output signal line of a conventional matrix switching circuit. In such a way, the length of transfer paths of all signals comes to the same. |
