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: |

Description: This chapter treats the design of linear-phase FIR filters. The assignments are divided in two parts, the first part focuses on the design of FIR filters using the window design method while the second part focuses on design of equiripple FIR filters using the Parks-McClellan algorithm, i.e. the remez algorithm in Matlab.

Description: 信道化发射信号仿真实验，2. 设计滤波器
应用Parks-McClellan optimal FIR filter order estimation设计滤波器，
参数：
内插I=16
内插前采样率50Hz
滤波器通带截止频率16Hz, 阻带起始频率25Hz；通带和阻带期望的幅度分别为1和0，起伏为1dB和40dB；
利用Parks-McClellan方法得到的频率向量fo，幅度向量ao和权值w设计最终使用的滤波器系数（可以使用remez方法，得到指定阶数的滤波器系数）。
显然，滤波器系数个数应为16的整数倍(Emulation experiment of channelized emission signal, 2. design filter
Using Parks-McClellan optimal FIR filter order estimation to design a filter,
Parameters:
Interpolating I=16
Pre interpolation rate 50Hz
The pass band cut-off frequency is 16Hz, and the band initiation frequency is 25Hz; the expected amplitude of the passband and stopband is 1 and 0, respectively, which fluctuate to 1dB and 40dB.
The frequency coefficients fo, amplitude vector AO and weight W obtained by the Parks-McClellan method are used to design the final filter coefficients (Remez coefficients can be used to get the filter coefficients of the specified order).
Obviously, the number of filter coefficients should be an integer multiple of 16.) Platform: |
