Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLHR are the ELF and VLF waves radiated by electric power systems at the harmonic frequencies of 50 or 60 Hz. Here we show for the first time large scale MLR observed simultaneously on ground and on board a low altitude satellite which is flying over the same zone.

EEPROM的几种保护方法 .rar EERROM的数据比较容易丢失,用这个方法-EEPROM several protection methods. Rar EERROM data more easily lost, Try using this method

HDB3（High Density Binary－3）码是AMI码的一种改进型。HDB3码保持了AMI码的优点，克服了AMI码在遇到连“0”长时难以提取定时信息的困难，因而获得广泛应用。CCITT已建议把HDB3码作为PCM终端设备一次群到三次群的接口码型。我本次毕业设计的主要内容就是基于Verilog HDL语言的HDB3编码器的设计，它所要达到的要求就是能从软件方面来实现HDB3编码器的基本功能，并能协调整个设计，使之达到预想的要求。设计的核心部分是：在Quartus Ⅱ的软件平台上，用 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
