narrowband noise signal的意思|示意

The system can issue a pure tone, tone twitter, narrowband noise and natural sound of the voice signal, and can adjust the loudness and frequency of the signals with some accuracy.

该系统能发出纯音、啭音、窄带噪声和自然声等声音信号，并可对信号进行一定精度的响度和频率调节。

For RFI and narrowband noise interferences, this dissertation studies notch filter and spectrum equilibrium and USES them to suppress narrow jammings in signal domain.

对于RFI和窄带噪声干扰，本文研究了频域陷波和谱均衡两种方法，并将之应用到信号域来抑制窄带干扰。

But to the CW pulse signal with changing carrier wave frequency, common filter cannot achieve narrowband filter, whereas broadband filter cannot reach the request of the signal-noise ratio.

可是，对于载波频率不断变化的CW脉冲信号，普通的滤波器难以实现窄带跟踪滤波，而宽带滤波又不能达到提高信噪比的要求。

The technique of orthogonal narrowband noise modulation is based upon the classical formula of narrowband random signal.

研究了由乘性和加性噪声的线性组合作为调制噪声的线性系统的随机共振。
