Transform/subband analysis and synthesis of signals
David M. Baylon, Jae S. Lim · 1990
A general relationship between transform representation and subband representa-tion of a signal is described in a unifying and tutorial manner. First, the transform and subband representations of a signal are described. It is then shown how one representation can be obtained from a simple rearrangement of the other representa-tion. Specific examples illustrate how a block transform can be implemented as an FIR subband filter bank, and vice-versa. The extension of the results is made for the two-dimensional case. Finally, applications to signal coding and adaptive amplitude modulation are discussed. 2
