Question

In a certain digital system, the decimal number from 000 through 999 is represented in bcd code. an odd – parity bit is also included at the end of the each code group(msb bit). examine each of the code groups below, and assume that each one has just been transferred from one location to another. some of the groups contain errors. assume that no more than two errors have occurred for each group. determine which of the code groups have a single error and which of them definitely have a double error. (hint: remember that this is a bcd code.)
