摘要 |
<p>A digital signal processing method and apparatus for processing a signal obtained on splitting the entire frequency band of an input digital signal into a plurality of sub-bands are disclosed. The entire frequency band of the input digital signal is split (5) into a plurality of sub-bands, and signals of each sub-band are allocated (24) to a plurality of sub-words divided from a word of the input digital signal. In allocating the signals, the information for reducing the noise in at least one of the sub-bands is allocated to the sub-word different from the sub-word to which is allocated the signal of the sub-band whose noise is to be reduced. <IMAGE></p> |
