ACF中包含两个m文件，一个是自协方差函数（可单独使用）。另一个是自相关函数计算，其调用autocov函数。(ACF contains two m files, one is self-covariance function (which can be used alone). The other is calculated from the correlation function, which calls autocov function.)

产生不同频率、不同幅度的两种正弦波信号 对两个信号进行叠加并做频谱分析 还原原来两个信号（LPF)(Produce different frequency, the two sine wave signals of different magnitudes of the two signals are superimposed and do spectral analysis to restore the original two signals (LPF))

调幅中波收音机的接收频率段为550KHz到1605KHz，中频为465KHz。调幅传输模型，对超外差式中波收音机建模(AM medium wave radio frequencies to 550KHz receiver to 1605KHz, IF is 465KHz. AM transmission model, modeling superheterodyne AM radio)

航管雷达的天线在水平方向上具有比较窄的波束，在垂直面上具有比较宽的波束，该程序仿真了航管雷达垂直面上余割型天线方向图(ATC radar antenna has a relatively narrow beam in the horizontal direction, has a relatively wide beam in the vertical plane, the program simulates air traffic control radar vertical plane cosecant antenna pattern)

大学数字信号处理实验题语音信号的高低通处理matlab程序答案(University of digital signal processing low pass of the experiment of the voice signal processing matlab program answer)

很好 我采用得是串行方式对bp网络进行训练，为何训练时误差dsum约来越大？？望指教！(good, I have used in serial mode is the right bp network training, training errors are about to dsum greater? ? Look weekend!)

log4j的配置文件！可以很好的配置log4j的程序，是一个标准模板(log4j configuration file! Log4j configuration can be a very good program, is a standard template)

说明：  主要包括了用gui设计的计算机界面，能通过控件进行计算(including the use gui computer interface design, control through calculated)

用Fourier变换求信号的功率谱(分段周期图法)(Calculate the power spectrum of signal using Fourier transform method)
