Abstract
A parallel-processing error correction system for digital data transmission employing a code-polynomial division circuit having a serial-type shift register for a cyclic code. Provided with null input lines, one for each data input line, a set of switches for selection between the data and null input lines, and another set of switches associated with buffer registers for series connection therebetween, the device can be readily adapted for any change in number of parallel input bits by switch operation.
