说明：  一个画一种Logistic Map 分岔图(bifurcation diagram)的程序，运行后，你们可以看到它与常规的非线性系统的行为不一样。该映射可以用如下方程表述: xn=1-a*x2n-1 其中，a――[0,2]. (Logistic Map a painting of a bifurcation diagram (bifurcation diagram) procedures, running, you can see it with the conventional non-linear system behavior not the same. The mapping equation can be expressed as follows: xn = 1-a* x2n-1 of them, a- [0,2].)

(1)设计一个数字低通滤波器．设计指标如下： 通带内幅度衰减人大于1dB 阻带内幅度衰减大于15dB (2)编制计算设计的数字滤波器幅度特性与相位特性程序，并进行实验验证； (3)编制实现该数字滤波器程序并且模拟实现数字滤波 ①分别让满足所设计滤波器的通带、过滤带、阻带频率特性的正弦波通过滤波器，验证滤波器性能。 ②改变正弦抽样时间，验证数字低通滤波器的模拟截止频率是抽样时间的函数。((1) Design a digital low-pass filter.

tvfemd可进行序列分解，比emd分解效果可能要好一点。(he sifting process is completed using a time varying filter technique.The local cut-off frequency is adaptively designed by fully facilitating the instantaneous amplitude and frequency information. Then nonuniform B-spline approximation is adopted as a time varying filter. In order to solve the intermittence problem, a cut-off frequency realignment algorithm is also introduced. Aimed at improving the performance under low sampling rates, a bandwidth criterion for intrinsic mode function (IMF) is proposed. TVF-EMD is fully adaptive and suitable for the analysis of linear and non-stationary signals. Compared with EMD, the proposed method is able to improve the frequency separation performance, as well as the stability under low sampling rates. Besides, the proposed method is robust against noise interference.)
