There are many digital communication systems where it is desirable to provide a flexible static and run-time digital diagnostic capability in the transmit path without increasing the digital data bandwidth or data rate required. This technique addresses this need by embedding digital diagnostic data into the primary digital transmit path. The diagnostic data is selec- tively embedded in a manner that requires no addi- tional data bandwidth or data rate, and avoids inter- rupting or causing prohibitive distortion in the primary digital transmit stream.
