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.
這樣的話，我們就不需要像對待窄頻帶信號那樣去觝消頻移了。
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.
本文提出在寬帶相關噪聲中，提取窄帶信號譜分量的一種高分辨率譜分析方法。
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，你的無線電信號可能會是一個窄帶信號，以區別於鄰近頻帶中其他的自然襍波。
