Abstract
An encoding apparatus is provided for encoding a wideband digital signal, comprising an input for receiving the wideband digital signal, a splitter unit for splitting the wideband digital signal into a number of M sub signals and a formatting unit for assembling digital information including said data reduced sub signals into a digital output signal having a format suitable for transmission or storage. During a repeated encoding and decoding of a wideband digital signal in a subband encoding/decoding system or a transform encoding/decoding system, signal degradation may occur. In order to avoid this, the apparatus further comprises a variable delay unit coupled between the input and the splitter unit, for realizing a delay, the length of which is controlled by a control signal, and a control signal generator unit for generating said control signal.
