- 中文摘要: 以馬克龍轉換所設計的多維濾波器可以直接轉換,轉置直接轉換,串行轉換,謝比謝夫和反轉謝比謝夫結構有效地執行。在這篇文章中,我們提出具最小記憶體的串行轉換結構,此結構只需要2NP列的儲存記憶體,此記憶體是(2NP+l)*(2NP+1)濾波器能達到的最小值。
- 英文摘要: The multidimensional finite impulse response (FIR) filters designed by the McClellan transform canbe implemented efficiently by the direct transformed structure, transpose direct transformed structure,cascade transformed structure, Chebyshev structure and the reversed Chebyshev structure. In this paper,the minimum storage implementation of the cascade structures is presented. For a (2NP+1)*(2NP+1)filter, it is found that implementation of the cascade transformed structure requires only 2NP rows ofstorage, which is the minimum storage the FIR filter can reach.
