书籍 LTE-Advanced+Relay+Technology
LTE-Advanced becomes a truly global standard for 4G cellular communications.
Relay, as one of the key technologies of LTE-Advanced, can significantly extend
the coverage, and improve the system throughput. LTE-A standards and tech-
nologies were described in several recent books where the limited pa ...
单片机编程 STM32，5110液晶显示超声波测距探鱼器200KHz，带电路图，精确到厘米
STM32，5110液晶显示声纳探鱼器200KHz，带电路图，精确到厘米 MC34063升压，大声压发射，实际板子上滤波电路没要（电路图上的滤波电阻电容电感没焊，开路或者短路）。一般200KHz的换能器在水里面的耦合比较好，在空气中发射出来的（或者接收的）强度很低。 用的MOSFET Relay，contact和release时间都可以做到很小，不过选的 ...
单片机编程 基于ATmega16的标记机控制系统
介绍了当前普通标记机控制系统现状及其存在缺点，给出气动标记机及相频修正PWM模式的工作原理。采用ATmega16单片机和USB转换RS232接口器件CH341T实现驱动控制系统与PC的实时通讯，标记控制系统可升级到USB接口。采用基于ATmega16的相频修正PWM替换555振荡电路产生的PWM，可直接通过软件调整PWM信号。使用达林顿三极管TIP122 ...
单片机编程 基于P87LPC764单片机的延时漏电继电器设计
介绍以P87LPC764型单片机为核心的延时型漏电继电器设计方案。该方案可供用户选择实现额定动作电流和5倍额定动作电流下不同的延时动作时间，并有重合闸设定选择功能。解决了以往传统分立元件带来的延时时间离散性大且不易实现的弊端。
Abstract:
 In this paper, the delay leakage relay based on P87LPC764 is int ...
