摘      要：An analytical derivation of quantization error in biter banks using additive and signal dependent noise models is *** coding gain over PCM-is derived for both noise models. Interesting properties of coding gain in optimized filter banks with an AR(1) input signal model, asymptotic performance of multirate systems, and the analytical constraints required to achieve such performance are discussed. Connections to the recent developments of optimal subband systems are presented.
