ABSTRACT:
A method for validating Manchester Encoded Gray Coded serial binary signals wherein the Manchester Encoded, Gray Coded data word is first tested for missing data bits by constructing first and second copies of the data word wherein the first copy has a one inserted in a position where a missing data bits is detected and the second copy has a zero inserted in a position where a missing data bit was detected. Thereafter, the first and second copies of the data word are then converted from Gray Code into corresponding coded binary words and the second binary word is subtracted from the first binary word to obtain an absolute value. Only when the absolute value is one is the missing bit the least significant and the received data word valid information.
