ABSTRACT:
A frame synchronization arrangement is disclosed for use in a digital data transmission system which utilizes a redundant data word transmission. A selected data word of each frame of data having a fixed location relative to the frame boundary is transmitted twice to provide a framing signal for the receiver circuit. At the receiver circuit the data is shifted through a shift register where a comparator checks predetermined locations of the shift register for redundant data words in the received data stream. Once the redundant data words are detected a valid word received signal is generated. The existence of the valid word received signal together with the known relationship between the location of the redundant word and the frame boundary is used to provide a framing signal.
