<p>CODE CONVERTER FOR POLARITY-INSENSITIVE TRANSMISSION SYSTEMS A polarity-insensitive code converter in which blocks of binary digits are translated into multilevel words having either one mode or another mode so that each coded word of one block of binary digits is the inverse coded word of the block of inverse binary digits. Hence the inversion of a code word during transmission results in the inversion of the recovered binary. With additional precoding and postcoding of the binary signal, polarity integrity of the original signal can always be restored.</p> |
