发明名称 Video signal correction device
摘要 A device for correcting line tilt which shows as a parasitic tilt of the plateaus of a video signal, the device includes an adder circuit (37) for adding a correction signal to a video signal to be corrected, the video signal to be corrected (36) being conveyed with its total passband to a first input (47) of the adder and the corrected signal being available at an output (35) of the adder. A second input (48) of the adder is coupled to an output of a frequency filter (38) to whose input (49) the video signal to be corrected is applied.
