Abstract
A circuit for coding a binary number represented in two's complement in a CSD-code wherein it is impossible for two immediately adjacent binary digits to respectively exhibit a '1'. The circuit is simply constructed and has a high operating speed. This is achieved by means of a series of logic components which respectively evaluate according to an exclusive-OR function and which create an output bit -1 from two respectively adjacent binary digits of the number to be encoded upon appearance of the bit combination 1,0. A series of second logic components create a CSD-coded bit combination 0, 1 from two respectively adjacent first logic components having the output bits 1,-1, but which accept the output bits of the remaining first logic components into the CSD-coded bit combination in unaltered fashion. The circuit is used in signal processors.
