改程序基于改进节点法（Modified Nodal Approach）与全矩阵技术在Matlab中实现线性电阻电路的符号分析。可以在GUI中描述待分析的电路结构、启动分析并直观的观察分析结果。在实现分析功能的同时，提供完整的编辑、输入保护以及数据保存功能。详细说明请见压缩包内文档。(Changed procedures to improve the node-based method (Modified Nodal Approach) with the full-matrix technology in Matlab to achieve linear resistance analysis of circuit symbols. GUI can be described in the circuit structure to be analyzed, start analysis and visual observation of the results of the analysis. Analysis function in the realization at the same time, provide a complete editing, input protection and data retention functionality.)

该程序是一个完整的模拟信号数字化传输系统的程序，它进过了PCM编码，2FSK调制解调和一个高斯白噪声，并有误码率的测量(The program is a complete program for the analog signal digital transmission system, it been to the PCM coding, 2FSK modem and a Gaussian white noise, and BER measurement)

声波方程正演,时间域，加吸收边界条件，可以自己编辑模型(Acoustic wave equation forward, time domain, plus absorbing boundary conditions can edit their own model)

在计算机上产生一组实验数据，首先产生一段零均值白噪声数据u（n）,令功率为 ，让u(n)通过一个三阶FIR： 得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形； (2)得出真实功率谱密度 . (3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。 (On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)
