Abstract
Circuit arrangement for the correction of data transmitted over a communication channel incorporates a shift register and a parity stage at the transmission side of the channel for generating parity bits, and similar equipment located at the reception side of the channel for generating similar parity bits. The parity bits are compared to provide syndrome signals, and the syndrome signals are stored in a syndrome shift register having a plurality of taps. A majority stage is effective to make corrections in the transmitted data when a majority of the syndrome signals at the taps of the syndrome register indicate an error condition. The taps of the shift registers employed for the parity generation and the taps of the syndrome shift register are spaced at unequal intervals. Four, six or eight taps are employed.
