书籍 Wireless Communications 2nd Edition
n the first part of this book, we give an introduction to the basic applications of wireless com-
munications, as well as the technical problems inherent in this communication paradigm. After a
brief history of wireless, Chapter 1 describes the different types of wireless services, and works
out the ...
书籍 ESD Protection Device and Circuit Design
The challenges associated with the design and implementation of Electro-
static Discharge (ESD) protection circuits become increasingly complex as
technology is scaled well into nano-metric regime. One must understand the
behavior of semiconductor devices under very high current densities, high
temp ...
书籍 RFID+Essentials
LIKE SO MANY OTHERS , THIS BOOK WAS WRITTEN BECAUSE WE COULDN ’ T FIND ONE LIKE IT . We
needed something to hand to all of those people who have come to us asking for “a good
book to read on RFID.” When we looked for candidates we found some great books, but
most were aimed at electrical engineer ...
书籍 The RF in RFID
To a quantum mechanic the whole universe is one godawful big interacting wavefunction ?
but to the rest of us, it’s a world full of separate and distinguishable objects that hurt us
when we kick them. At a few months of age, human children recognize objects, expect
them to be permanent and move con ...
书籍 Fundamentals_of_Global_Positioning_System3
If one examines the current literature on GPS receiver design, most of it is quite a
bit above the level of the novice. It is taken for granted that the reader is already at a
fairly high level of understanding and proceeds from there. This text will be an
attempt to take the reader through the conc ...
书籍 Structure and Interpretation of Signals
Signals convey information. Systems transform signals. This book introduces the mathe-
matical models used to design and understand both. It is intended for students interested
in developing a deep understanding of how to digitally create and manipulate signals to
measure and control the physical wo ...
技术资料 基于Proteus的单片机模数转换电路的设计与仿真
以单片机控制A/D转换器TLC549为例,对A/D转换器的主要技术指标进行了分析研究,在Proteus平台下,完成了A/D转换电路的构建,采用器件工作时序方式进行程序编写,借助仿真图表、虚拟仪器等工具对A/D转换的数据进行测量并对失调误差、增益误差、微分非线性、积分非线性和转换时间等重要参数进行了详细分析。结果表明:使用Proteus软 ...
技术资料 基于数字电路的八路抢答器的设计与实现
抢答器是一种智力竞赛常用的器件,抢答器的设计方法千差万别,文章利用常用的数字电子器件,设计了八路抢答器电路的设计、仿真及实现的全过程,提出两种可行的设计方案:方案1采用74ls373实现电路锁存,74ls148实现电路编码,74ls74及数码管实现电路显示;方案二采用CD4511BCN和LMC555CM集成电路及数码管实现抢答器的控制和显示。本 ...
技术资料 4G移动通信技术权威指南：LTE与LTE-Advanced.4G LTE.LTE
PrefaceDuring the past years, there has been a quickly rising interest in radio access technologies for providingmobile as well as nomadic and fixed services for voice, video, and data. The difference indesign, implementation, and use between telecom and datacom technologies is also becoming moreblu ...
技术资料 高级PID控制算法.
Simulation can provide a lot of information about what the system is doing. We canadd the effect of different element, like Encoder resolution, ADC sampling rate, etc and understand how does it affect the system. Another benefit is the possibility to slow down the process, to gain insight on what ha ...
