Abstract :
A tandem differential pulse code modulation (DPCM) system structure is developed and the design problem formulated. In the simplified case of cascaded quantizers, the low-to-high and high-to-low bit rate tandems are examined and the performance limitations discussed, Finally the performance of tandem DPCM systems operating at various bit rates is evaluated by simulation.
