这个文件编程实现了正弦调频的频谱图分布和乔伊-威廉斯分布，通过观察我们可以看到不同时频分布算法实现的不同特点(This file programming the frequency spectrum of a sinusoidal FM distribution and Joy- Williams distribution, we can see by observing the time-frequency distribution of the different features of algorithm implementation)

MATLAB环境下的Simulink仿真平台，构建PCM编码与解码电路图，对模拟信号进行采样、量化、编码, 将编码后的信号输入信道再进行PCM解码，还原出原信号.建立仿真模型,分析仿真波形。(MATLAB environment Simulink simulation platform to build PCM encoding and decoding circuit diagram of the analog signal is sampled, quantization, encoding, the encoded signal input letter Road and then the PCM decoding, restore the original signal. Establish simulation model, analyze simulation waveforms.)

实现图像变暗，给图像家噪声，锐化处理的MATLAB原码，可用于图像处理领域(MATLAB source code can be used to darken the image noise to the image home, sharpening the field of image processing)

Create TSOM 2D/3D image it is lithograpy semicondutor defect method

信号系统上机实验代码与指导书，采样、连续卷积、连续运算、连续系统(Machine experimental code and instructions on signal systems, sampling, continuous convolution, continuous operation, continuous system)

数字信号处理软件设计，能够产生常见的数字信号如：正弦波 三角波 随机信号 以及高斯噪声，并对其进行频谱分析 同时也包括FIR IIR滤波器设计，并对产生的数字信号进行滤波(software design of digital signal processing that can generate many signals ,analysize their frequency Spectrum and design filter(FIR、IIR)to filter.)

希望对大家有所帮助，祝大家学习进步，有时间共同探讨问题 (Would like to help everyone, I wish everyone to learn and progress, have time to explore the issue of)

这是我学习时候，我的课本上的课后习题，我把他整理出来！希望大家能有所收益！(This is my study, my after-school textbook exercises, I took him out of order! Hope that we can get any benefit!)
