Theory of Subband Decompositionof audio subband coding shown in Figure 5.1.1. Let us say that one needs to sample the signal at a 10-kHz rate which corresponds to a bandwidth of 5 kHz.* If we need an accuracy of 16 bits, then we need to transmit or store a total of 160 Kb/s. As shown in Figure 5.1.1, in practice, the energy near
