DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同，代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键，10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求： (1) 根据键盘输入的符号，利用MATLAB产生对应的DTMF信号；(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图；(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 (DTMF (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.)

视频抓帧，抓到连续图像每一帧。适合做视频的朋友(Video frame, catch caught continuous image each frame)

说明：  使用matlab模拟迈克尔逊干涉等厚、等倾干涉图样(Simulation of Michelson interference equal thickness interference pattern with MATLAB)

matlab下的数字图象处理例程,其中有关图片文件只要随便找个图片就可以了(matlab under the digital image processing routines, including the relevant picture file as long as you can not find a picture of the)

说明：   M-file for Project 1 on line parameters and circuit models in Chapter 3 m1.m determines the RLC parameters of the line from its physical description and then computes the ABCD matrix and the circuit parameters of the series RL, nominal pi and equivalent pi model of the line. It computes and plot the receiving-end real and reactive power circle diagram of the line assuming that the voltage magnitude at the sending- and receiving-end are kept constant.

说明：  matlab上的EMD经验模态分解的源代码(matlab on the EMD EMD source code)

Fruit Fly Optimization for ZSCORE

说明：  多目标优化，非遗传算法，matlab编程(Multi objective optimization)

上课时做的matlab图像处理实验，包括卷积，拉普拉斯变换，罗伯特算子，种子算法，等等(Matlab class to do the image processing experiments, including convolution, Laplace transform, Robert operator, seed algorithm, and so on)

修改的卡尔曼滤波程序，适用于AIS航迹滤波，和雷达的航迹关联(Modified Kalman filtering procedures applied to AIS track filtering, and radar track association)
