如何设计和制造最佳的或最优的滤波器。最佳滤波器是指能够根据某一最佳准则进行滤波的滤波器。

维纳滤波器最小均方误差准则

（滤波器的输出信号与需要信号之差的均方值最小）

最大输出信噪比准则最佳滤波器最小二乘准则最佳滤波器统计检测准则最佳滤波器在一定条件下，这些最佳滤波器与维纳滤波器是等价的。

-How to design and create the best or the best filter. The best filter is the best according to a filter filtering criteria. Wiener filter MMSE criteria (filter output signal with the need to signal the difference between the mean square value of the minimum) the maximum output signal-to-noise criteria for the best filter criteria for the best least-squares statistical detection filter the best filter criteria in certain conditions, these best filter and Wiener filter are equivalent.
