ABSTRACT:
A video signal sampling apparatus for sampling an input analog video signal by use of a sampling clock, and producing a digital signal which represents a level of a resultant video signal sample as a digital video signal is disclosed. The video signal sampling apparatus includes N (N being an integer equal to or greater than 2) converters for sampling the input analog video signal by use of N sampling clocks having phases that are different from each other to produce N digital signals which represent levels of N resultant video signal samples respectively, and a selector for selecting one digital signal from the N digital signals produced by the N converters in order that an amplitude of the digital video signal output to the outside is maximized.
