Connected with the practice of design on the integrated wiring system, this thesis will discuss three problems: the difference between frequency bandwidth and transmitted velocity, the selection of shield and non shield twisted pair, the design of systematical protection on electricity.
结合综合布线系统设计实践 ,论述了(频率)带宽与传输速率的区别 ,屏蔽与非屏蔽双绞线的选择及系统电气防护设计三个问题。
The X-band section of this joint has three channels:two for high power and one for low power,and has a frequency bandwidth of Δf = 1GHz,while its L-band section has two channels both for high power and has a frequency bandwidth of Δf= 140MHz.
该关节 X 波段为三路,(频率)带宽为:△f=1GHz,两路高功率通道,一路低功率通道;L 波段为两路,(频率)带宽为:△f =140MHz,两路均可用于高功率通道。
The thesis summarizes the application and progress of HFIRF carcinoma operation under mild hurt system recently.
