BCD- kood on sobiv binaarkoodis olevate arvude esitamiseks kümnendkujul. BCD-koodi kasutavad nt. numbertabloode dekoodrid. NRZ-kood Non-return to zero encoding is commonly used in slow speed communications interfaces for both synchronous and asynchronous transmission. Using NRZ, a logic 1 bit is sent as a high value and a logic 0 bit is sent as a low value (the line driver chip used to connect the cable may subsequently invert these signals). A problem arises when using NRZ to encode a synchronous link which may have long runs of consecutive bits with the same value
