摘要:
A code converter includes:
extraction means (31) for extracting a reference level from a binary-coded input signal, which is offset at the predetermined voltage level and varies arbitrarily with the same polarity as the voltage level; twos-complement conversion means(32), connected to the extraction means (31),for converting the reference level into a twos-complement value; and creation means (33), connected to said extraction means (31) and twos-complement conversion means(32) for adding an output signal of the twos-complement conversion means (32) and the binary-coded input signal, thereby producing a bipolar binary-coded output signal to which a polarity bit is added.
