PURPOSE:To cancel noises to a neighboring signal line, by generating complementary signals based on a specified signal, arranging signal lines for said two signals in a symmetrical pattern so that said two signal lines are twisted at a constant pitch. CONSTITUTION:Based on a signal line 1, signal lines 2 and 3, which have a complementary relationship, is formed. The two lines are twisted at a constant pitch. Capacitances 1 and 2 and 3 and 4 are perfectly equal. Coupling noises 1 and 2 to a signal line 4 are 180 deg. out of phase perfectly and cancelled. Therefore, the noises do not appear on the signal line 4. |
