摘要
FIR滤波器具有严格的线性相位和任意的幅度特性 ,能满足数字电视对信号的实时处理和高保真度的要求 ,目前已有计算机程序可资利用 ,使得FIR滤波器的设计大大简化 ,因而使线性相位FIR滤波器在数字电视的亮、色信号分离电路中得到了广泛的应用。
The linear phase place with strictness and the wanton range characteristic of FIR wave filter can meet the digital TV requisition for real-time processing and hi fi (high fidelity) of the signal. Computer programs can already be utilized at present to make the design of FIR wave filter simplify greatly. Therefore, the linear phase place FIR wave filter is widely used in the brightness and the color of signal while separating the circuit in Digital TV.
