Abstract

PURPOSE:To enhance a capability for removing interference signals, by a device wherein both normal video and MTI video are independently provided with circuits generating gate signals to remove pulse-type interference signals from the normal and MTI videos. CONSTITUTION:Interference signals in MTI video generate corresponding gate signals. The output from the gate signal generator 307 enters the video gate circuit 313. Normal video simultaneously entering the video gate circuit 313 is cut off while gate signal is appearing. Thus, the normal video with interference signal being removed exits from the video gate circuit 313. The output from the OR gate 312 enters the video gate circuit 314. MTI video simultaneously entering the video gate circuit 314 is cut off while the gate signal is appearing. Thus, the MTI video, with interference signals being removed, appears from the video gate circuit 314.
