Abstract
A scalable encoder having a first encoder, a decoder and a second encoder includes, above that, a phase distorter to reduce a non-linear frequency-dependent phase distortion introduced by the first encoder or by the decoder, which results in an increased difference signal of a comparator. Thus, a difference signal with less energy is obtained that the second encoder can encode with less bits, that is with a higher bit efficiency.
