Abstract
PURPOSE: To realize the transmission of the high-quality code by providing several pairs of systems which transmit or reproduce the encoded signals after changing them into complements, changing simultaneously the correspondence code of the system into the complement and then using this complement for check and control of the error.
CONSTITUTION: The output of signal source 1 and clock pulse source 3 within the code transmission part are encoded through encoder 2, and the output is applied to complement unit 5 to be changed into the complement with every second fixed bit via the gate pulse of processor 4 and then to transmit output 6. Output 6 is then is formed into about a pair of codes through delay units 9 and 10 at the reception part and then supplied to complement reloaders 13 and 14 with delay equivalent to the complement code. Then the complement is reloaded at the fixed time position and by the output of process part 16 connected to synchronous isolator 15, and the output is compounded by the action of switch 22 to be applied to reloader 24 via different switch 23. Switches 22 and 23 are actuated by the output of adder 17, subtractor 18 and processor 21, and each complement is used to carry out check and control of the error.
