Abstract
The present invention relates to a ground isolation circuit for use in connecting electronic circuits at the pre-stage and the post-stage having signal lines assigned for a plurality of channels, wherein the interconnection of the two electronic circuits is performed by employing a shielded signal cable for each channel, discrete ground terminals are provided at either of the electronic circuits, one for each channel, and thereby each shielding braid of the shielded signal cable is connected independently to the discrete ground terminal with every channel. Accordingly, no loop circuit is formed through the shielding braids, thus resulting in no induced noise even if there is an interlinkage of external radiation noise with the shielding braids.
