Abstract

The invention relates to a process and a circuit for producing a delay. In known processes for phase adjustment, a first signal component of a TV signal is delayed by filtering a second signal component. In the invention, the content of an image store with first and second signal components (Y, C) is emitted by means of an additional line address counter so that the first signal component (Y) of a line n and the second signal component (C) of a line n + 1 are used and so that the second signal component (C) is fed to a vertical interpolation filter. The solution proposed by the invention is used preferably in digital image processing systems.
