摘要：A multi-rate filter bank including an anti-aliasing filter, a plurality of multiplierblock modules, a folding block, and a data composer is disclosed. The anti-aliasing filterreceives an anti-aliasing input signal. The multiplier block modules receive an originalsignal and sequentially generate a plurality of processed signals. The multiplier block

modules also receive a plurality of block input signals and a select signal. Each of themultiplier block modules is configured into a decimation block or an expanding anti-aliasing filter according to the select signal. The folding block receives the select signaland a folding input signal and generates a folding block output signal. The data

composer receives and composes the folding block output signal and the outputs of themultiplexer block modules and the anti-aliasing filter and generates an anti-aliasing filteroutput signal.
