Abstract
To convert a 12-bit data word into an 18-bit code word, the 12-bit data word is divided into the 8 high-order bits and the 4 low-order bits. The 8 high-order bits are converted into 12 bits and the 4 low-order bits are converted into 6 bits, thereby creating an 18-bit code. This enables conversion using small-scale conversion tables.
