Abstract
The present invention relates to a signal diagnostic method for a triple information transmission system. According to this method, using a transmission signal transmitted latest among three transmission signals of three channels, the synchronizing signal parts of the respective transmission signals are synchronized so as to align the heads of information signal parts of the transmission signals, whereupon any error in the information signal parts of the transmission signals is detected. The three transmission signals of the three channels are temporarily stored in three registers. The storage time intervals of the transmission signals in the registers are determined by the transmission time differences between the respective transmission signals and the latest transmission signal. Upon lapse of the predetermined storage time intervals, the transmission signals are fetched from the respective registers.
