| Abstract: | In order to construct multiple-channel filters, the property of the sum of all the elements in each row of Slant matrix was investigated. A low-pass filter was constructed by the first row while a group of high-pass filters constructed by all the other rows. Meanwhile, by polyphase factorization, it was proved that the low-pass filter satisfies perfect reconstruction condition. Finally, two examples on signal decomposition were proposed, and the validity of constructed multiple channel decomposition filters was verified. |
