matlab计算测量信号的包络线

模态振型分解法,讲的很详细，对于初学者很有用(Modal decomposition method, said very detailed, very useful for beginners)

说明：  根据语音信号的特点给出有关滤波器的性能指标：1）低通滤波器性能指标，fp=1000Hz，fc=1200 Hz， As=100dB，Ap=1dB；2）高通滤波器性能指标，fc=2800 Hz，fp=3000 Hz As=100dB，Ap=1dB；3）带通滤波器性能指标，fp1=1200 Hz，fp2=3000 Hz，fc1=1000 Hz，fc2=3200 Hz，As=100dB，Ap=1dB。用IIR对其分析，最后，利用MATLAB中的函数freqz画出各滤波器的频率响应。(This article according to the IIR filter and the FIR filter characteristic, uses the bilinearity method of transformation under the MATLAB bad boundary to design IIR and to design the FIR numeral filter separately with the window box number, and carries on the analysis to the gathering pronunciation signal, and finally gives IIR and FIR to the pronunciation filter effect.)

matlab的一个小程序，for循环，这事最基础的程序，大家一定要掌握的(matlab a small program, for circulation, this most basic procedures, the U.S. must find the)

说明：  matlab新安江三水源模型，包括产流 汇流 分水源 河道演进(matlab Xinanjiang three water models, including river water runoff evolution confluence points)

经典的多点法形状复原算法的逐次2点法和逐次3点法的程序。本程序对当存在随机误差和系统误差时产生的评价误差进行了分析。(classic multi-point method shape recovery algorithm Successive 2:00 and 3:00 successive Act procedures. When the right procedures exist random error and systematic error, caused by the error of evaluation analysis.)

说明：  角谱仿真，仿真通过某一孔径的角谱衍射结果(Angular spectrum simulation)

This code demonstrate compressive sensing example. In this example the signal is sparse in frequency domain and random samples are taken in time domain.

convex_letterV 光波通过V型窗口时的衍射效果模拟源程序(convex_letterV light waves through the V-shaped window of diffraction effects simulation program)

This code is to calculate wind power from wind speed data and power curve data
