基本解释

It is simple in use and its computation amount is about no more than that of a 4 point FIR DF.
该方法计算简单，计算量仅相当于4点FIR数字滤波器的计算量。
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.
在数字信号滤波器设计中，论文着重论述了线性相位FIR滤波器的设计，并将TOP—DOWN的设计思想贯串始终。
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.
尽管窗函数法与频率抽样法在FIR数字滤波器的设计中有着广泛的应用，但两者都不是最优化的设计。
