High-speed - timing signal generator, in particular for producing frame - or half image blanking periods in a raster scanning - video system

摘要

the present invention is a high frequency, high resolution programmable zeitsignalgenerator is proposed, a periodic time signal generated during a period which, in terms of the time resolution of the generator is long.the zeitsignalgenerator (26), in particular for the produce of the composite synchronisierungssignals (and many related signals) for a video fernsehsignal is used, contains a small hochgeschwindigkeitsspeicher random access.where each word corresponds with a zeitzustand and each ausgangssignalbit on the video synchronisierungssignal related signal returns.other speicherbitausgangssignale work in connection with control and zeitschaltkreisen for sequential memory (72) to address, while the memory (72) is allowed in a given state for predetermined duration to remain and cyclically selected condition effects of repeated.the speicherwort composition is interpreted in such a way that the use of a small, fast memory allows for a precise management of complex over relatively long intervals of time rahmenperioden with great flexibility, must be provided.
