说明：  用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱(Simulink tools with the code (S-Function mode), resulting in a single-path Rayleigh Road, the Doppler spectrum for the classical spectrum)

本文介绍了基于MATLAB软件在《信号与系统》课程教学中的仿真实验,通过抽样信号的表征、周期方波信号的傅立叶级数分解与合成、余弦信号的相加与相乘、RLC带通滤波器的频率特性等仿真实验,说明了将MATLAB应用于教学实践中的重要作用和意义。(This article describes the MATLAB-based software in the " Signals and Systems" course teaching simulation, by sampling the signal characterization, cycle square wave signal of the Fourier series decomposition and synthesis, and the sum of cosine signal is multiplied, RLC bandpass filter the frequency characteristics simulation, MATLAB used to illustrate the important role of teaching practice and significance.)

说明：  齐声效应，能模拟几个演奏者同时演奏，但实际只有一个演奏者。(Chorus effect, can simulate several players while playing, but actually only one player.)

this is a matlab program for af relaying,node formation

用matlab实现从原始视频中提取关键帧，并且自动生成新视频，新视频只由关键帧组成从而实现视频总结。(Using matlab realize extracted from the original video key frame, and automatically generate a new video, new video key frame composed by only enabling the video summary.)

该文件运用matlab仿真工具仿真通信中的关键技术之一，锁相环。采用不同的调制方式。(The document the use of simulation tools for communication matlab simulation of one of the key technologies, phase-locked loop. Different modulation.)

单一频率的正弦相关法动态测试系统的测试方法简单，不需要对系统进行辨识。只需要观察被测系统输出信号的相差和幅值变化。通过扫频的方法测量在不同的频率点下的幅值和相位变化。在工程应用中，只需要知道被测系统的相位变化在正常的范围内就可以视系统的动态性能正常。该仿真算法只是建立了一个模型。在实际运用时还需要变换测试信号的频率和周期。(A single frequency sinusoidal correlation method of testing dynamic testing system is simple, does not require system identification. Only need to observe the difference between the measured system output signal and amplitude change. Swept through the method of measurement points at different frequencies under the amplitude and phase changes. In engineering applications, only need to know the system under test changes in the normal phase it may be possible within the framework of the dynamic performance of the system to normal. The simulation algorithm is the establishment of a model. In the practical application of test signals also needed to change the frequency and periodicity.)
