<p><P>PROBLEM TO BE SOLVED: To eliminate GND noise superimposed on a video signal by a simple configuration. <P>SOLUTION: The video signal with GND noise outputted from an external device 200 for a video signal output superimposed thereon and a GND signal with GND noise having the same instantaneous value as the GND signal outputted from the external device 200 for a video signal output superimposed thereon are acquired in a common-mode signal elimination circuit 100A for a video signal, and the a subtraction circuit 104 subtracts the video signal and the GND signal to thereby eliminate the GND noise superimposed on the video signal. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
