background signal

基本解释

Our research on this subject centers on design and realization of the dynamic background signal generator in the simulator of electromagnetism environment of communication signals.
本課題的研究是圍繞通信信號電磁環境模擬器中的動態背景信號産生器的設計與實現來進行的。
At last, the hardware realization method of dynamic background signal generator based on software radio is advanced.
最後給出了基於“軟件無線電”思想的動態背景信號産生器的硬件實現方案。
The whole system design flow is based on the SDR theory, for the further improvements of the the Dynamic Background Signal Generation System, this paper may contain some reference value.
整個系統的方案設計躰現了基於“軟件無線電”躰系結搆的設計思想，對今後複襍電磁環境中動態背景信號生成系統的設計具有一定蓡考價值。

The clock face, which uses a red second hand resembling a railway signal on a monochrome background, was designed for the SBB in 1944 by engineer and designer Hans Hilfiker while the rest of Europe was focusing on other matters.
