信号与系统 相关分析与卷积运算的试验报告上课写的(Signal related to the system analysis and convolution computing class written test report)

说明：  频域的模态参数识别方法之一，可以对振动信号进行分析处理，得出结构的固有频率，阻尼比，振型系数，方法很好，程序完整，(Frequency-domain modal parameter identification methods that can analyze the vibration signal processing, draw the structure of natural frequencies, damping ratio, mode shape coefficient, very good method, program integrity,)

This file includes the source code of the Uncoded+Coded QPSK with Viterbi (Term & hard decision) decoder.

这是线性议程组的直接解法，有十种不同的解法（这与迭代解法是不同的）……(This is the direct linear solution of the agenda of groups, there are dozens of different method (which is different from the iterative solution) ... ...)

椭圆检测。利用霍夫变换的原理实现椭圆的检测，并在图中标记出来，可用于方向盘的检测。(Ellipse detection. Using the principle of detecting the implementation of elliptic Hof transform, and marked in the graph, can be used to detect the steering wheel.)

说明：  计算温度场分布的程序，希望对有关人员有所帮助，因为时间关系里面多了一些无用的说明，请自己删除(calculate the fieled of temperature)

线性调频信号发生器，能够改变它的一些参数得到不同的线性调频信号，程序还是不错的(Linear FM signal generator, can change some of its parameters are different linear FM signal, the program is good)
