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: |
