Description: 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 circle, the minimum-phase filter constituted. Platform: |

Description: FIRPM公园，麦克莱伦最佳equiripple FIR滤波器的设计。乙= FIRPM（不适用，女，甲）返回一个长度为N +1线性相位（真实，对称系数）FIR滤波器具有最佳逼近到所需的频率响应的F和描述在极小极大意义的。F是成对频带边缘载体，以递增0和1之间秩序。 1对应于奈奎斯特频率或采样频率的一半。至少有一个频段必须有一个非零宽度。 A是一个真正的载体，作为F的指定由此得到的滤波器的频率响应所需的幅度B相同大小- FIRPM Parks-McClellan optimal equiripple FIR filter design.
B=FIRPM(N,F,A) returns a length N+1 linear phase (real, symmetric
coefficients) FIR filter which has the best approximation to the
desired frequency response described by F and A in the minimax sense.
F is a vector of frequency band edges in pairs, in ascending order
between 0 and 1. 1 corresponds to the Nyquist frequency or half the
sampling frequency. At least one frequency band must have a non-zero
width. A is a real vector the same size as F which specifies the
desired amplitude of the frequency response of the resultant filter B. Platform: |
