PAL test pattern generator
A stable reterence signal is essential whenever you want to adjust a television or a video monitor. Special integrated circuits have been developed that enable a PAL/NTSC colour test pattern generator to be built trom a minimum of components. Untortunately, these lCs are generally expensive as well as hard to obtain, and that is why we propose to do without one tor a change.
