ABSTRACT:
A code converter includes an extraction device for extracting a reference level from a binary-coded input signal, which is offset at a predetermined voltage level and which varies arbitrarily with the same polarity as the voltage level. A twos-complement conversion device, connected to the extraction device, converts the reference level into a twos-complement value. A creation device, connected to the extraction device and the twos-complement conversion device adds an output signal of the twos-complement conversion device and the binary-coded input signal, thereby producing a bipolar binary-coded output signal to which a polarity bit is added.
