书籍 Radio Frequency Identification and Sensors
There is an unprecedented enthusiasm for radio frequency
identification (RFID) technologies today. RFID is based on the
exchange of information carried by electromagnetic waves between a
label, or tag, and a reader. This technology is currently in full
economic expansion, which has manifested itself ...

EN 300220-1V2.4.1 Electromagnetic compatibility and Radio spectrum Matters (ERM);Short Range Devices (SRD);Radio equipment to be used in the 25 MHz to 1 000 MHz frequency range with power levels ranging up to 500 mW; Part 1: Technical characteristics and test methods
技术资料 EMC的定义
EMC即电磁兼容，EMC是英文Electromagnetic Compatibility的缩写。在我们生活、工作的环境中，时时刻刻都存在着各种各样的电磁能量，这些电磁能量可能会使电子设

Feeding antennas with proper signals can be difficult. The signal is often described as a voltage, and voltages are not well defined in electromagnetic wave formulations. There are several tricks to model voltage generators in such situations, and one is the magnetic frill. This model shows the basi ...

书籍 EMI+Protection+for+Communication+Systems
Communication today is not as easy as it was in the past. Protecting numerous com-
munication services, which are operating in the same or adjacent communication
channels, has become increasingly challenging. Communication systems have to be
protected from both natural and manmade interference. Elec ...
书籍 Radio Wave Propagation
One of the prerequisites for the development of telecommunication services is the
understanding of the propagation of the waves, either acoustic, electromagnetic,
radio or light waves, which are used for the transmission of information.
In this work, we shall limit ourselves to the study of radio wa ...
教程资料 XAPP1065 - 利用Spartan-6 FPGA设计扩频时钟发生器
 
Consumer display applications commonly use high-speed LVDS interfaces to transfer videodata. Spread-spectrum clocking can be used to address electromagnetic compatibility (EMC)issues within these consumer devices. This application note uses Spartan®-6 FPGAs togenerate spread-spectrum ...

模拟电子 降低EMI和保持高效率D类放大器在便携式产品中的应用
Abstract: Class D amplifiers are typically very efficient, making them ideal candidates for portable applications that require longbattery life and low thermal dissipation. However, electromagnetic interference (EMI) is an issue that commonly accompanies theClass D switching topology. Active-emiss ...
