Abstract
It is shown that for the realizable subband coding of a wide sense stationary Gaussian source, with the implied separate encoding of the subband signals, the encoding performance is generally inferior to the rate-distortion function of the source. It is established that, for small encoding distortion, except for special cases, the subband coding is generally suboptimum.<>
