Title: Digital receiving circuit for TDM telephone networks - uses three-section 8-bit shift register handling data block words
Inventor: ZEMANEK JOSEF DIPL ING
IPC: H04Q11/04
Filed: 1978-07-25
Abstract: The digital receiving circuit is suitable for digital signals in block form. The signal blocks are fed to a three-section shift-register. Each 8-stage section handles the synchronization word and signalling word, the remaining two being assigned to the two data words. A comparator monitors the last stage of the shift-register for the appearance of the synchronizing bit pattern. When the comparator's output is positive, after the counter reached its end position, a flip-flop is reset and prevents further data flow into the shift-register. The counter is started by a signal indicating the position of the block w.r.t. time and counts up to the expected block length.
