Abstract

PURPOSE:To cut off troubled lines so that the majority output does not receive any influences from the troubled lines, by connecting an operation mode setting circuit to the circuit of the multiplexed synchronizing system. CONSTITUTION:The multiplexed synchronizing system is constituted with a triple line selecting circuit group III, double line selecting circuit groups 12 II, 23 II and 13 II and a single line selecting group I, and selecting circuits III0-III3, 12 II0...13 II2, and I1-I3 are installed to each circuit group III, 12 II, 23 II, 13 II, and I. Moreover, a common operation mode setting circuit M III is installed to each selecting circuit III0-III3 of the circuit group III, and, also, each common operation mode setting circuit M II12, M II23 and M II13 are installed to each circuit group 12 II, 23 II, and 13 II, respectively. These respective circuits M III, M II12...M II13 are used as AND circuits which input-enable signals EN1-EN3 from the first line to the third line, and the output of each circuit is given to each selecting circuit III0-III3, 12 II...13 II as triple line operation mode setting signals m III, n II12...M II13, and thus cutoff of troubled lines becomes easier.
