技术资料 基于Proteus可视化设计

在单片机项目中,开发者不仅需要考虑硬件选择,方案设计,还要编写功能代码,仿真测试等。而对于非计算机专业的初学者来说,编程难度较大。Proteus可视化设计方法,利用流程图代替编写代码这一特点,大大减低了难度,从而激发学生学习积极性。In the single chip project, developers not only need to consider hardware selection ...

单片机编程 MAXX9257 MAX9258芯片可编程SerDes持续时间计算

The MAX9257/MAX9258 programmable serializer/deserializer (SerDes) devices transfer both video data and control signals over the same twisted-pair cable. However, control data can only be transmitted during the vertical blank time, which is indicated by the control-channel-enabled output (CCEN) sig ...

电路图 AZ1117H

The AZ1117 is a series of low dropout three-terminal regulators with a dropout of 1.15V at 1A output current. The AZ1117 series provides current limiting and thermal shutdown. Its circuit includes a trimmed bandgap reference to assure output voltage accuracy to be within 1% for 1.5V, 1.8V, 2.5V, 2.8 ...

论文 Bi-density twin support vector machines

In this paper we present a classifier called bi-density twin support vector machines (BDTWSVMs) for data classification. In the training stage, BDTWSVMs first compute the relative density degrees for all training points using the intra-class graph whose weights are determined by a local sc ...

技术资料 LCL滤波器

Abstract—This paper deals with various active damping approaches for PI-based current control of grid-connected pulsewidth-modulation (PWM) converters with LCL filters, which are based on one additional feedback. Filter capacitor current, as well as voltage feedback for the purpose of resonance dam ...
