BIPOLAR SIGNAL TRANSMITTING SYSTEM

摘要

PURPOSE:To save a required power supply capacity as much as possible and also to suppress the increase of noises in power supply by designing the system that the phase of a bipolar signal transmitted from a bipolar signal transmitting circuit belonging to a group and the phase of a bipolar signal transmitted from that belonging to the other group are not overlapped with each other. CONSTITUTION:The bipolar signal transmission circuits BS1a-BSxb are divided respectively into two groups; bipolar signal transmission circuits BS1a-BSxa (group a) and BS1b-BSxb (group b). Clock signals cka and ckb inputted to gates Gp and Gm provided corresponding to the groups (a) and (b) are set so that the conducting period t/2 of the gates Gp and Gm of the groups (a) and (b) is not overlapped with each other. As a result, the phase of a positive or a negative peak value, +V1 or -V1 in a bipolar signal voltage va transmitted to relay lines L1a-Lxa corresponding to the group (a) and in a bipolar signal voltage vb transmitted to relay lines L1b-Lxb corresponding to the group (b) is not overlapped with each other.
