Abstract
After a short review of the basic principles of PCM and DPCM coding it is shown that combining the two methods in one coding system results in a combination of some favorable properties. The hybrid D-PCM system combines the bit-rate reduction of DPCM with a low error sensitivity. In another approach the hybrid D-PCM system is also derived from a usual DPCM system with a leaking integrator. Two different applications of the hybrid D-PCM system illustrate the possibilities and the performance of the hybrid D-PCM system.
