A non-linear coding means connected to an controlled by the output of the forecast means adaptively varies a non-linear component of such reference amplitude. The reference amplitude to be coded is supplied to the coding means and the reference amplitude preceding the reference amplitude to be coded is supplied to the forecast means. | |
