摘要
本文讨论了用加权平方误差最小准则设计FIR数字滤波器的方法,由滤波器的模型构造一线性系统,通过辩识系统参数方法来设计滤波器系数.这一设计方法具有很高的设计精度,编程方便,容易使用.
This paper discusses the design method of FIR digital filters under the weighted least - squares error criterion. We create a linear system from the model of the filters and design the coefficients of the filters by the identification of system parameters. This design method has a high accuracy. It is convenient to program and easy to use.
