1) time division frequency transmission
频率分时传输
1.
To obtain pressures and temperatures of the formations in oil and gas well testing,a downhole wireline remote telemetry method is developed by using time division frequency transmission technology in the Pressure-Low-Temperature-Low mode.
为获取井下待测地层的压力/温度,提出了一种“压力-空-温度-空”缆芯复用的频率分时传输方法。
2) time/frequency transfer
时间频率传输
1.
In order to improve the precision of time/frequency transfer via fiber,a method of digital phase compensation is proposed.
为提高光纤时间频率传输的精度,提出了数字移相补偿方法。
3) carrier waves with different frequency
频分传输
1.
Its basic principle is that: multiplex video signal modulates carrier waves with different frequency.
视频总线技术是实现多传感器视频资源共享的新概念,它的基本功能是以总线形式传输搜索雷达、跟踪雷达、电视/红外等视频信号,它的基本原理是多路视频信号调制不同的载波,利用频分传输的原理,用一根同轴电缆传输至各显控台,每个显控台解调恢复出这些信号供给综合显示用,这样可以大大减少整个系统视频信号的传输电缆。
4) FDM
频(率)分(割)多路传输(制)
6) frequency-division multiplex
频率划分多路传输
