无线射频识别技术(RFID)是自动识别技术的一种高级形式。随着信息化技术的不断发展，无线射频识别技术(RFID)的应用也越来越广泛。本书主要介绍了无线射频识别技术的基本工作原理和具体应用，并列举了大量的应用实例，如动物识别管理、配送中心管理、矿井管理、停车场管理、军事物流运用等-Radio frequency identification technology (RFID) is the automatic identification of an advanced form of technology. As information technology continues to develop, radio frequency identification technology (RFID) applications are increasingly widespread. This book introduces the radio frequency identification technology, the basic working principles and specific applications, and listed a large number of application examples, such as animal identification management, distribution center management, mine management, car park management, the use of military logistics

RFID读卡器设计的重要参考资料.很不错的-RFID reader reference design important. Very good

chirp fourier transform 线性调频Z变换(CZT) 的matlab功能函数，该方法通过CZT变换获得精确的等价于离散傅里叶变换结果的间谐波信号的频率分布估计值,可以得到精确的各次谐波和间谐波参数,利用该函数相同采样频率下该方法的检测精度更高。(This routine allows the evaluation of the DFT over an arbitrary range of frequencies as its name implies this lets you zoom into a narrow portion of the spectrum.)
