radio frequency signal meaning in Chinese
射频信号
Examples
- The lower resistance should select properly , too big to make radio frequency signal drive collector current too little , too small to make amplifier instable easily
下偏电阻要选取适中，过大会使射频信号推动集电极电流的能力过小，过小容易使放大器不稳定。 - Scope of application : the product is fit for the transmission of radio frequency signals in radio equipment or in electronic equipment adopting similar technologies
产品用途:产品适用于煤矿井下无线电通讯设备和采用类似技术的电子装置的有关无线电子设备中传输射频信号。 - Suitable for transmitting 1ghz and following radio frequency signal , spread the digital signal under audio frequency 150khz and following simulation signal 2048kbits frequently
适用于传输1ghz及以下的射频信号，传频音频150khz及以下的模拟信号2048kbits以下的数字信号。 - Often , this is used to make appliances appear to " talk " or wall outlets appear to be " sending radio frequency signals " , or strong radio interference will be found to emanate from a point in mid air
这常常使设备好像是在“谈话” ，或墙缝处好像在“传送无线电频率信号” ，或强大的无线电干扰会被发现仿佛是来自于空中任何一处。 - The radio frequency receiver supports interface for instrument and base station and air interface for mobile station , and it takes the task of magnifying low noise and down - convert and digital baseband processor filtering and magnifying intermediate frequency to reverse link signal . the digital baseband processor samples the received signal after down - convert radio frequency signal to intermediate frequency signal and processes other processing and supports interfaces to computer , next sends data to computer . the gps receiver supports interface for instrument and gps system , and receives gps system signal , next it demodulates the correlative information and sends out benchmark clock signal we need
射频接收部分主要为仪器和基站、移动台提供空中接口,其主要任务是在反向链路上对接收到的射频调制信号进行低噪声放大、射频下变频变换、中频滤波放大等;数字基带部分为对接收信号变频为中频后进行a / d采样,以及其他的rsp处理并和计算机提供接口,将数据送至计算机进行后台处理、显示等; gps接收机部分为仪器和gps系统提供接口,接收gps系统信号并解调相关信息,输出所需的电文及时钟基准信息等。
