NR METHOD FOR POWER SYSTEM

Simulation of basic circuit eletric

用来估计病态线性方程组正则化求解时的误差。(To estimate the error of regulation method for the ill-conditioned system of linear equations)

SAR 成像算法 matlab程序源代码，包含子程序，有仿真结果，(SAR imaging algorithm matlab source code, including subroutines, there are simulation results,)

这是数模中有关层次分析的源码，相信有需要的人!(This is the model on several levels of analysis of the source code, I believe those who are in need!)

1．产生一个连续信号，包含低频，中频，高频分量，对其进行采样，进行频谱分析，分别设计三种高通， 低通，带通滤波器对信号进行滤波处理，观察滤波后信号的频谱。 2.采集一段含有噪音的语音信号（可以录制含有噪音的信号，或者录制语音后再加进噪音信号），对其进行 采样和频谱分析，根据分析结果设计出一合适的滤波器滤除噪音信号(1. Produce a continuous signal, including low-frequency, medium frequency, high-frequency components, its sampling, spectral analysis, are designed for three high-pass, low pass, band-pass filter the signal filtering treatment to observe the signal spectrum after filtering. 2. Acquisition section of the speech signal contains noise (can record a signal containing noise, or voice recording, additional noise after the signal), its sampling and spectral analysis, based on an analysis of the results to design a suitable filter to filter out one noise signal)

二次相关时延估计算法，仿真效果图效果很好，经过验证可以准确估计时延(Secondary related delay estimation algorithm simulation renderings good results, proven to accurately estimate the delay)
