TELEVISION SYNCHRONIZATION SIGNAL AND TEST SIGNAL GENERATOR, AND TELEVISION SYSTEM COMPRISING SUCH A GENERATOR |
摘要 |
A television base signal and test signal generator comprises a first memory for storing n eight-bit words (n being a positive whole number) located by a pair of indices (i, j) and a second memory for storing t four-bit words (t being a positive whole number) located by an index k. A first counter and a second counter supply respectively the index i associated with the word to be read in the first memory and the index k associated with the word to be read in the second memory. The index j associated with the word to be read in the first memory corresponds to the value of the four-bit word supplied by the second memory. The two memories are programmed so that at all times the eight bits of the word read in the first memory define entirely the desired base signals and test signals. |
