Subband analysis

Webband analysis and synthesis can be shown in the form of a combined block diagram of fig.11.4. 11.3 Conditions for perfect reconstruction in analysis-synthesis filters We are … WebAn analysis filterbank splits the input signal with sampling rate Fs by dividing it into 32 equally spaced subband signals with sampling rate Fs /32. In each of the 32 subbands, 12 consecutive samples are assembled into blocks with the equivalent of 384 input samples.
