Aiken code

(data)An alternative form of the Binary Coded Decimal (BCD)system for encoding numbers. Where BCD encodes each decimaldigit in normal binary, Aiken code uses the encoding shownbelow. This is supposed to be less prone to corruption.

The following table shows the encoding of each decimal digit,D, in BCD and Aiken code:

D BCD Aiken0 0000 00001 0001 00012 0010 00103 0011 00114 0100 01005 0101 1011 (inverted 4)6 0110 1100 (inverted 3)7 0111 1101 (inverted 2)8 1000 1110 (inverted 1)9 1001 1111 (inverted 0)

The Aiken code was probably designed by Howard Aiken in the1940s or 1950s for use in data transmission.

Compare: Gray code.
