Cellphones send signals to nearby towers via radio frequency waves, a form of energy similar to FM radio waves and microwaves.
手机经过射频电波(一种与调频电波和微波类似的能量方式)，将信号发送至左近的信号塔。
The filter used a kind of general structure, whose central frequency located nearby the rotation speed to reduce the unbalance vibration.
该陷波滤波器采用通用式结构，其中心频率分布在转子转速附近以抑制不平衡振动。
Zero placement method in the frequency domain is utilized to design robust multi-hump EI optimal arbitrary time-delay filter (OATF) by placing two or more filter zeros nearby the system poles.
采用频域的零点配置方法，通过在系统极点附近配置多个滤波器零点设计强鲁棒性的多峰极不灵敏（E I）最优随机时滞滤波器。
Nearby room boundaries can create frequency response errors (called comb filtering) due to wave reflections combining in the air.
声频设备附近的墙壁会反射声波，空气中的声波叠加，产生频率响应误差(亦称梳状滤波器)。
With this system, two nearby repeaters can share the same frequency pair (for receive and transmit); so more repeaters (and hence more users) can be accommodated in a particular area.
经过这个系统，两个临近的中继器能够运用不异的频率停止接纳和传布，如许更多的中继器和挪动设备能够在统一个区域内正常工作。
