In the evening this station change frequency and broadcast on another band 该电台晚上改变频率,在另一波段播音
Study of the rain attenuation in the satellite broadcast of Ku band Ku波段卫星广播中雨衰现象的研究
In this architectonic system, a large number of meteorological data are transported by broadcast through the satellite and ground broad band from CMA to province, municipality, and county meteorological bureau. 这种体系结构下大量的数据通过卫星和地面宽带以广播方式传输到各省、市、县气象单位,各级气象部门都要设置相应的系统维护机构,大大的增加了系统的维护难度和成本。
As for the FM broadcast with high frequency and narrow band, the principle and realization of bandpass sampling are researched later. And the effect of bandpass over-sampling to SNR is simulated thereafter. 针对调频广播信号的高频窄带特性,研究了带通采样原理及实现,并仿真研究了带通过采样倍数对SNR的影响。
Besides the digital television broadcast, the digital broadcast technology also includes two big aspects which are the data broadcast and the interactive service, its typical application including software downloading, wide band Internet service as well as interactive television and so on. 除了数字电视广播外,数字广播技术还包括数据广播和交互业务两大方面,其典型应用包括软件下载、宽带Internet服务以及交互电视等。数据广播实际上是广播电视增值业务的基础。
Discussions on Feasibility of Expanding SW Broadcast Band from Spectrum Monitoring and International Coordination 从频谱监测和国际协调探讨短波广播频段扩展的可行性
Its coherence is strong, and it is broadcast live, concert, dance, directing the band, performing any of the links are not allowed any flaws. 它的连贯性之强,又是现场直播,演唱、舞蹈、指挥、乐队、表演等任何一个环节都不允许出现任何纰漏。
Based on this study, growers can either broadcast at sowing or band along the rows at a later time when corn is emerged, which will give flexibility to N saturated reference plots establishment. 基于本研究,种植者既可以在播种时撒施氮肥也可以在出苗后沟施氮肥,这就使氮饱和参考小区的构建具有一定的灵活性。
