脉冲频带 [mài chōng pín dài]
[电子] pulse band
- 还介绍了超宽带系统的两种结构：基于脉冲无线电（Impulse Radio）的结构和多频带调制结构。
Besides, we introduce two schemes for UWB system: Scheme based on Impulse Radio and System based on Multi-band Modulation. - 超宽频脉冲的延续时间很短，因此必须在横跨好几GHz的连续频带内运作。结果是，脉冲愈短，占据的频谱愈宽。
BECAUSE OF THEIR EXTREMELY short duration, these ultrawideband pulses function in a continuous band of frequencies that can span several gigahertz. - 大多数超短脉冲激光器输出波长范围均集中在近红外和中红外波段，而短波长宽频带超短脉冲激光具有更大的应用潜力。
Most of waveband of ultra-short laser is concentrate on mid-infrared and infrared, but there are more potential applications of short-wavelength and broadband frequency laser.
