Abstract
It is shown that, for the 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. Exceptions are when the source is white or when the filters are ideal (brickwall)
