Abstract

1. A method of converting digital input signals of a light waveguide transmission system from a first binary code comprising 32 different code words each comprising five binary digits corresponding to 32 possible amplitude values into output signals which occur in a second binary code comprising code values comprising six binary digits having a positive and a negative mode, where the mode corresponding to the continuous digital sum occurs at the end of the preceding code word comprising binary digits, wherein the 32 possible amplitude values (0...31) of the input signal are sub-divided into two equal sized sections each comprising 16 code words where the first section comprises the amplitudes values between a lowest amplitude value (0) and a first middle amplitude value (15) and the second section comprises the amplitude values between a second middle amplitude value (16) and a maximum amplitude value (31), wherein the code words for the positive mode of the output signal of the first section are selected to be such that the greatest possible conformity occurs between the input and output signals, and wherein for the lowest amplitude value of the second section the code word (49) for the positive mode corresponds to the inverted code word (14) of the negative mode of the highest amplitude value of the first section, and the code word (49) for the negative mode corresponds to the inverted code word (14) of the positive mode of the highest amplitude value of the first section, characterised in that for the second lowest amplitude value of the second section, the code word (57) for the positive mode corresponds to the inverted code word (6) of the negative mode of the second highest amplitude value of the first section, and the code word (17) for the negative mode corresponds to the inverted code word (46) of the positive mode of the second highest amplitude value of the first section, that the code words for the other amplitude values of the second section are formed correspondingly, and for the highest amplitude value of the second section, the code word for the positive mode corresponds to the inverted code word of the negative mode of the lowest amplitude value of the first section and the code word for the negative mode corresponds to the inverted code word of the positive mode of the lowest amplitude value of the first section, so that a diagonally inverted symmetry occurs between the two sections of the amplitude values of the input signal and the output signal.
