电子芯片sn75453b详细说明 的中文资料 (Chinese information detailed electronic chip sn75453b)

1. 采用BP神经网络设计男女生分类器。采用的特征包括身高、体重、是否喜欢数学、是否喜欢文学、是否喜欢运动共五个特征，BP神经网络包含一个隐层，隐层结点数为5。要求：自行编写代码完成后向传播算法，采用交叉验证的方式实现对于性能指标的评判（包含SE,SP,ACC和AUC，AUC的计算可以基于平台的软件包）。(. using BP neural network to design the classifier for male and female students. The features include height, weight, whether they like mathematics, whether they like literature, and whether they like sports. The BP neural network contains a hidden layer, and the number of hidden nodes is five (5). Requirements: self compiled code, post propagation algorithm, cross validation method to achieve performance evaluation (including SE, SP, ACC and AUC, AUC calculation can be based on platform software package).)

计算几何,英文版,写的十分详细,适合初学者入门学习,老手也可丛中学到不少知识(Computational geometry, English, written in great detail, suitable for beginners study entry, a pair of veterans may also learn a lot of knowledge)

基于AT89C51系列单片机的音乐盒，依据单片机的定时中断以及蜂鸣器的发声原理，通过KEIL编译程序，并将其通过烧写工具下载到单片机实验箱中，从而设计制作出一个八音盒。此程序使用C语言编写，实现对单片机的控制。

说明：  合成孔径雷达( SAR) 是一种高分辨率成像雷达，可以在能见度极低的气象条件下得到类似光学照相的高分辨雷达图像。 BP算法基于时域处理回波信号，利用脉冲压缩技术实现距离向匹配滤波，方位向分辨率通过沿回波曲线进行相干叠加实现。(Synthetic aperture radar (SAR) is a kind of high-resolution imaging radar, which can obtain high-resolution radar images similar to optical photography under extremely low visibility weather conditions. BP algorithm is based on time-domain processing of echo signal, using pulse compression technology to achieve range matched filtering, azimuth resolution is achieved by coherent superposition along the echo curve.)

搜寻最短延时的交织m序列伪码，可选择m序列的长度，自动产生生成多项式-Search for the shortest delay interwoven m PN sequence can choose the length of m sequence, automatically generating polynomial

基于psim的SVPWM仿真，利用C-BLOCK模块搭建。(The SVPWM simulation based on PSIM is built with the C-BLOCK module.)

这是一个用multisim10做的一个万用表，用的全波整流，欢迎借鉴。-This is a multisim10 to do with a multimeter, using the full-wave rectifier, welcome to draw on.

通过远程控制四套除尘风机一次启动，通过保护器反馈信号控制风机保护，并且反馈运行状态，通过延时躲开信号反馈冲击等(Through remote control, the four sets of dedusting fan start once, control the fan protection through the feedback signal of the protector, and feedback the running state, avoid the signal feedback, impact and so on through the time delay)
