FIR滤波器设计中往往是线性相位，但不是最小相位，所以它的零点有部分在单位圆外。把单位圆外的零点映射到单位圆内，构成最小相位滤波器。-FIR filter design is often the linear phase, but it is not minimum phase, so it has some of the zeros outside the unit circle. To zero outside the unit circle is mapped to the unit ci

单输入输出系统的预测控制，主要是对最小相位系统的跟踪给定值的仿真。-Single input-output system predictive control, mainly simulation of minimum phase system to track a given value.
