您要查找的是不是：
- echo frequency content 回声频率容量
- In some cases trialled, the low frequency content of music signals became excessively boosted. 有时试行的低频讯号成了音乐的内容过于刺激。
- This paper discusses the application of joint estimation of DOA and Doppler velocity in passive bistatic radar, and analyzes emphatically the passive detection of target echo frequency in passive bistatic radar. 将 DOA与多普勒速度的联合估计定位应用于双基地雷达 ,重点分析双基地雷达系统中对目标回波频率量的无源检测方法。
- In this case, because the gain and input are at the same frequency content, a dc component, which a lowpass filter can easily detect, is present at the amplifier’s output. 像这样，因为增益和输入是同样频率，低通放大器容易探测到的直流器件，呈现放大器输出。
- These methods strive to maintain the high frequency content of the image consistent with the horizontal and vertical scaling, while reducing the effects of aliasing. 这些方法都是努力维持图像的高频分量，使之与在水平和垂直缩放相中保持一致，同时减少混叠的效果影响。
- The earthquake ground motion is characterized by its three tightly correlated attributes: amplitude, frequency content, and duration.Its panorama can hardly be viewed from a single perspective. 地震动特性有三个要素:振幅、频谱和持时,三者之间相互作用,孤立研究任何一个方面都难以全面地反映地震动作用的全貌。
- Secondly, we generated different single frequency sections by rearranging frequency contents. 然后按照频率重排产生共频率的剖面；
- Earth filtering effect rapidly attenuates high frequency contents and distortswavelet phase characteristics. 大地滤波作用不仅引起高频成分的迅速衰减，而且造成子波相位特征的畸变。
- The excursion of instantaneous frequency representation will be resulted when EFT is applied to signals with rapidly varying frequency contents. 对于具有恒定幅度的调频信号而言，瞬时频率代表了其全部的信息，可以据此对信号进行识别和分类。
