Abstract
A method and apparatus for performing digital signal error detection through the use of a string of received incoming system address bits. The incoming address bits are divided into groups according to whether they contain a high value of '1' or a low value of '0'. At least one address parity bit is then generated from each group and used in checking the integrity of data received.
