A scrambler for use with thermometer-code digital signals and having a number of interconnected identical switching cells in the form of swapper cells with two inputs and two outputs. A control signal determines whether the inputs are connected directly or reversely to the outputs. The control signal is developed by logic circuitry which receives as inputs the two swapper cell input bits and a state bit representing the integrated difference of past swapper output signals.
