1 ?群延迟时间 ... group delay distortion 群延迟失真,群时延畸变... group delay time 群延迟时间... group depreciation 分组折旧,分类折旧... 2 ?群延时时间 ... group delay time 群延迟时间 group delay time 群延时时间 group delay 群时延 ... 3 ?时间 4.8扫描线路测试仪 网络中许多重要的传输参数都与频率有关,如 组延时时间(Group Delay Time)和衰减失真测试 (Attenuation Distortion Test)等,在测试这些参数时, 测试仪器必须工作在合适的频率之下。
- 1
The oblique sounding is one of the powerful tools, by which an oblique ionogram is obtained with the group path or time delay against operating frequency. 斜向探测是电离层探测的主要方式之一，它能够获得电波传播群时延和频率关系的电离图。 - 2
The sample rate, filter corner frequency, settling time, group delay and output word rate will be reduced also, as these are proportional to the external clock frequency. 由于采样速率、滤波器转折频率、建立时间、群延迟和输出字速率与外部时钟频率呈比例变化关系，因此这些参数也会相应降低。 - 3
The reflection spectrum, time delay, and group velocity dispersion (GVD) of the gratings are analyzed. 并对此种光栅的反射谱，时延及群速度色散进行了理论分析；
