Abstract
A communication cable for connecting a computer main body with a monitor to display an image on the monitor and to reduce electromagnetic wave interference, includes a plurality of video signal lines for transmitting video signals and ground lines respectively corresponding to the plurality of the video signal lines, each of the plurality of the video signal lines including a filter including an inductive element which is inserted in series with respect to the video signal line and a capacitive element which is connected in parallel between the video signal line and the ground line corresponding to the video signal line wherein respective nodes between the plurality of the capacitive elements each of which is included in the filter of the video signal line and the ground lines corresponding to the plurality of the video signal lines are connected with a common line. Thus, electromagnetic wave interference can be removed without variation of the video signal level.
