Theory of Subband Decomposition band without losing any fidelity, as the high pass band has very little energy. Thus, for this case, we need only a total of 80 Kb/s + 40 Kb/s = 120 Kb/s. Thus, we have achieved, for this example, a compression ratio of 4/3. Of course, one need not be limited to only two subbands. Actually, for spe

Applications of Subband and Wavelet Transform in Digital Communicationsource coding which removes redundancy, channel coding introduces some redundancy in a predetermined fashion to improve the fidelity of the signal output. The channel has noise and interference, which causes error in the output. By introducing an n-bit codeword for a k-bit of information when n>k, th
