ABSTRACT:
A digital signal transmission system and equipment therefor in which digital signals sequentially sent out from an encoder side are compared with set values in each of comparators at a decoder side, for sending out signals from the comparators when the values of the digital signals are larger than the values set in the comparators and for suspending signals from all of the comparators if the values of the digital signals are smaller than those set in the comparators, while output from the comparator having the set value nearest to the signal value is utilized for inverting other comparators so as to suspend outputs from these other comparators for effecting stable signal transmission through simple construction.
