Question


This is my code, the optimization is not good, I hope to find a good way to optimize the coefficients of this IIR filter? I can get good results using the yulewlaker equation,
clc,clear; [freq,H]=freqAndHFunction(); freq=[0,freq]; magnitude=[0,H]; % 采样率 Fs= 16000; % 进行插值 interp_freq = linspace(0,...

关于水声换能器的信号仿真 About modeling and simulation of hydroacoustic transducers
本人课题准备根据水声换能器的发射响应仿真信号通过换能器的数据，把水声换能器看成一个线性系统，把发射电压响应看成换能器的频率响应。建立频率响应模型，进行非线性优化。现在的问题是选择合适的算法进行最优化模型的拟合，第二个问题是有没有别的方法对根据发射电压响应，...
