Abstract
Method and apparatus for transferring digital data in a bit stream consisting of digital data words each of which words includes data bits and a parity bit are disclosed. Except for the word parity bits, the stream is transferred without additional overhead bits such as start and stop bits employed in an asynchronous transmission data format or synchronizing characters employed in a synchronous transmission data format. Method and apparatus for locking onto the parity bit of such a bit stream are disclosed which allow for digital data transfer in this format.
