高频率

Due to FC nature of the repeater, FC repeater uses twice as much frequency as the conventional CS, PS, or amplifiers. Thus, one must pay special attention not to let the signal leaks out to the un-intended coverage area, especially areas under noticeable frequency blockage. When used for outdoor application, it should only be used for low traffic areas.

由于变频直放机的工作需要占用比一般设备（基站、手机、基站放大器等）多一倍的频率资源，所以在应用中要注意：用于室内覆盖时避免直放机与手机通信时的信号泄漏到话务量很高的室外引起频率阻塞；用于室外覆盖时，应该使用在基站稀疏，话务量低的区域。

A silent communications system in which nonaural carriers, in the very low or very high audio-frequency range or in the adjacent ultrasonic frequency spectrum are amplitude- or frequency-modulated with the desired intelligence and propagated acoustically or vibrationally, for inducement into the brain, typically through the use of loudspeakers, earphones, or piezoelectric transducers.

在一个无声的通讯系统中，一个非常低或者非常高的音频，或者接近超声波的频率，其波幅或者频率被调节到具有相当被理解能力并以合适的振动方式或者以听觉传输的方式来刺激一个昏睡者的大脑。典型的装置是用扬声器，耳麦，或者变压器。

According to the morphological characteristic variations,4 body measurements,i.e.withers height,body length,chest girth and fore shin circumference were measured on the spot,and 25 items in 11 types of appearance character were describedand their phenotype frequencies were computed,14 coat color were classified andtheir frequencies were computed.

根据形态学特征的变异特点，对17个山羊群体的四项体尺即体高、体长、胸围、管围进行了现场测定，对11个类型的25项外形特征指标进行了分类描述和表型频率估计，对14种毛色类别进行了表型分类和频率估计。

The number of the frequency division of the method and the circuit structure thereof do not influence the highest frequency of the working circuit. The normal work of the frequency division circuit can be at a comparatively high clock frequency, and the clock frequency division can be realized in the manner of cascade connection of the frequency division circuit so that the scale of the circuit realization can be properly reduced.

本发明所述方法及其电路结构的分频数大小不影响电路工作的最高频率，可以使分频电路正常的工作在相对很高的时钟频率，而且可以通过分频电路级联的方式实现时钟分频，从而可以适当减小电路实现的规模。
