frequency modulated example signal

基于multisim的调频接收机 包含混频中放低放鉴频(FM receiver based on multisim mixing in the lower release contains discriminator)

说明：  生成全排列矩阵，含有三个小程序,也含有说明(Order to generate the whole matrix, which contains three small programs, but also contains a description)

matlab实现，验证奈奎斯特采样定理，对信号求傅里叶变换的数值解，数值求解，画出时域图，频域图(matlab implementation, verification Nyquist sampling theorem, Fourier transform of the signal find the numerical solution, numerical solution, draw the graph in time domain, frequency domain graph)

三组二维输入向量P，以及其相对应的三个类别TC，目的是构建一个PNN网络对输入向量进行正确分类。(Three sets of two-dimensional input vector P, and their corresponding three categories TC, aimed at building a PNN network correct classification of input vectors.)

IMAGE_CONTRAST is a MATLAB function which carries out a simple contrast enhancement operation on an image. Note that MATLAB s image processing toolbox includes a functions such as nlfilter which can do a more sophisticated treatment of images. But the purpose of this example is to demonstrate the process of image enhancement in a way that is clear enough to understand quickly.

虚拟激励法在汽车工程中的应用示例，可以求振动的功率谱密度。(THE APPLICATION OF MULTIPLE-POINT PSEUDO EXCITATION METHOD TO TRACKED AMBULANCE VIBRATION-REDUCTION SYSTEM RANDOM VIBRATION ANALYSIS)

this is for qrs detection

说明：  详细的介绍了音频模糊聚类的算法，非常的容易搞懂(Detail audio fuzzy clustering algorithm, the easier they get to know very much)
