CB:载波频带
“载波频带”(Carrier Band)在专业通信领域中常被缩写为“CB”,以方便日常书写与口头交流。这一术语主要用于无线电广播、通信工程及相关技术场景,指代用于传输信号的特定频率范围。缩写形式不仅提高了沟通效率,也使专业人员在技术讨论中能够更便捷地引用这一概念。

- 结果表明:雷达工作频率、带宽以及路径电子总量(TEC)是影响成像质量的决定因素。
- A simple model of calculating the linewidth enhancement factor ( a factor ) is presented based on the theory of Henry. Interband transition, free carrier absorption and band gap narrowing are considered in this model.
- 本文从Henry提出的基本理论出发,考虑了带间跃迁、带隙收缩和自由载流子的吸收三方面因素对线宽展宽因子(α因子)的影响,给出了一种计算半导体激光器a因子的简单方法。
- In the modern digital wireless communications, digital data are modulated onto a RF carrier and transmitted to a receiver, which down-converts the RF carrier to base band for demodulation.
- 在现代无线通信系统中,数字信号被调制到载波上,并经过天线发送到接收器。在接收器中,经过调制的射频信号被下混频至基带,以便于解调的进行。
- In the modulation of amplitude, there are ordinary amplitude modulation ( the standard amplitude modulation AM ), restraint signal carrier Double Side Band ( DSB ) and restraint carrier Single Side Band ( SSB ) according to the numbers of frequency spectra of the selected modulated signals.
