用RFM001多页读写32MM的TI玻璃管卡,采用严格的时钟控制-RFM001 pages to read and write using the TI glass 32mm cards, using a strict clock control

无线收发模块NRF24E1的开发源码，EEPROM下载范例，对有志与无线系统开发的同志应该有帮助-wireless transceiver module NRF24E1 open source, EEPROM Download example, with the right interested in the development of wireless systems should help comrades

采用全波电磁仿真软件，仿真设计了超宽带缝隙结构的平面等角螺旋天线和阿基米德螺旋天线，两种天线都采用同轴电缆直接馈电的方式。(this paper proposes an idea about experimental teaching mode reforming of microwave technology and antenna courses by introducing the full wave elect.)

qt下RFID标签的读取，是毕业设计的内容，因此可以保证运行-qt under the RFID tag reader is the graduation project, so can guarantee operation

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.)
