基于锁相环Top-down的建模方法在MATLAB环境下建立数字锁相环完整的仿真模型，并用SIMULINK对数字锁相环的仿真模型进行仿真。　(Top-down phase-locked loop based on the modeling method in MATLAB environment DPLL set up a complete simulation model, and use of digital phase-locked loop SIMULINK simulation model simulation.)

通过最小二乘法及SVD-TLS法对同一谱进行了功率谱分析，并比较了不同阶数下，最小二乘法的效果(By least-squares method and SVD-TLS method to the same spectra of the power spectrum analysis, and compare the number of different bands under the effect of least-squares method)

介绍自适应均衡算法RLS的基本代码，可以仿照编写相关程序(RLS adaptive equalization algorithm introduces the basic code, you can follow the preparation of related procedures)

说明：  插值，只用于精确的数据，因为通过指定的准确点拟合曲线。这个算法很有用，通过几个给定的点来绘制平滑曲线。(Use only for precise data, as the fitted curve passes through the given points exactly. This routine is useful for plotting a pleasingly smooth curve through a few given points for purposes of plotting.)
