Abstract
Known ADPCM transcoders use processors for coding and decoding, which are time and power consuming. Such a known ADPCM transcoder comprising one processor for coding and decoding can handle four channels, while according to DECT twelve channels need to be available, which requires three known ADPCM transcoders. By delaying signals in an ADPCM transcoder, it is no longer necessary to use processors, but, instead of said processors, logic elements can be used, which is very advantageous, because of such an ADPCM transcoder being able to handle sixteen channels.
