To reduce chip size and lower cost by using a method of multiplexing a device to filter a plurality of signals, the present invention provides an apparatus for filtering the plurality of signals, comprising: a group of storage units, for storing the plurality of signals, wherein the group of storage units comprises a plurality of storage units, each of which is used to store corresponding signal segments in each signal and output the stored signal segments in a predefined order; and a processing module, for weighting and combining the output signals from the group of storage units, to obtain a plurality of filtered signals corresponding to the multiple channels of signals. The group of storage units may further comprise a group of combining units, for combining output signal segments from the storage units to be processed with a same weight value. The present invention further provides the corresponding method for filtering a plurality of signals. With the method and apparatus of the present invention, the filter size may be reduced significantly and the cost may be lowered. |
