narrow-band signal

基本解释

As a result, there is no need to compensate for the drift as is the case with a narrow-band signal.
这样的话，我们就不需要像对待窄频带信号那样去抵消频移了。
In this paper, a high resolution technique for detecting the presence of frequency components of a narrow-band signal in the broad-band correlated noise is examined.
本文提出在宽带相关噪声中，提取窄带信号谱分量的一种高分辨率谱分析方法。
Your radio transmission, furthermore, would probably be a narrow-band signal, to distinguish it from other transmissions in neighboring bands as well as naturally occurring noise.
此外，你的无线电信号可能会是一个窄带信号，以区别于邻近频带中其他的自然杂波。
