在数字通信系统中，滤波器是其中重要部件之一， 滤波器特性的选择直接影响数字信号的恢复。在数字信号接收中， 滤波器的作用有两个方面，第一是使滤波器输出有用信号成分尽可能强；第二是抑制信号带外噪声，使滤波器输出噪声成分尽可能小，减小噪声对信号判决的影响。 (In digital communication system, the filter is one of the important components of the filter characteristics of the choice of a direct impact on digital signal recovery. In the digital signal receiver, the filter s role is twofold, first is to filter the output useful signal components strong as possible the second is the signal-band noise suppression, so that filter output noise components as small as possible, reducing the noise on the signal the impact of decision.)
