fir df

基本解釋

It is simple in use and its computation amount is about no more than that of a 4 point FIR DF.
該方法計算簡單，計算量僅相當于4點FIR數(shù)字濾波器的計算量。
In the design of digital signal processing filter, thesis mainly discuss the design of FIR DF and take advantage of the TOP-DOWN idea from begins.
在數(shù)字信號濾波器設計中，論文著重論述了線性相位FIR濾波器的設計，并將TOP—DOWN的設計思想貫串始終。
Although window function method and frequency sampling method are widely applied to the design of FIR DF, an optimum design of FIR DF can't be obtained by these two methods.
盡管窗函數(shù)法與頻率抽樣法在FIR數(shù)字濾波器的設計中有著廣泛的應用，但兩者都不是最優(yōu)化的設計。
