Abstract
To minimize the number of positions to be altered in a transition from one output data word to the next in a scrambler for scrambling successive, thermometer coded binary input data words comprising N bits into corresponding successive output data words also comprising N bits, the scrambler is adapted, if the number of bits of one binary value has increased from one input data word to the next, to maintain bits of said one binary value in positions in the corresponding output data word where the previous output data word had bits of said one binary value, and to randomize the remaining bits of said one binary value to positions in the corresponding output data word where the previous output data word had bits of the other binary value.
