中文摘要 | 當設計一個轉換帶很窄的二維數位濾波器,若以傳統方法來實現,其階數必定會 較高,同時在設計與實現所遭遇之困難度亦會相對的增加。為了解決此一問題,本篇論文藉 由雙重轉換過程,利用數個相同低階的子濾波器串接在一起來設計與實現高階的二維數位濾 波器。 |
英文摘要 | FIR subfilters are cascaded together to design a 2-D FIR digital filter by means of the process of double transformation in this paper. In order to design a 2-D digital filter with a narrow transition band, the orders will be very high by making use of the traditional method. And the difficulty of design and implementation will be increased exponentially. In order to deal with this problem, we take advantage of a number of identical low-order subfilters cascaded together to design a high-order filter. |
