intermediate frequency signal meaning in Chinese
中频信号
Examples
- 3 . accomplished the hardware design of intermediate frequency signal processing 4 . accomplished the software design of intermediate frequency signal processing
3 .完成了中频信号处理的硬件设计。 4 .完成了中频信号处理的软件设计。 - In the digital intermediate frequency project , the intermediate frequency signal is converted to digital signal directly into the dsp chip , then it is be processed by dft
数字中频方案将中频信号直接通过a / d转换后送入dsp芯片进行dft变换，最后得到待测信号频谱的采样序列。 - By analysis of the intermediate frequency signals which through eight antennae and receiver channels , eight channels radio spatial spectrum direction finding system can reach the purpose of finding radio direction
八通道无线电空间谱测向系统通过分析经过八路天线和接收机通道以后的中频信号达到确定无线电信号方向的目的。 - In this thesis , aimed at the above - mentioned two - side problems , based on analyzing the theory of lfmcw radar ranging deeply , we implement the work of intermediate frequency signal processing
本论文针对上述两方面的问题,在深入分析lfmcw雷达测距理论基础上,在工程上完成了一部8mm毫米波线性调频连续波测距雷达的中频信号处理工作。 - Due to the hardware characteristic ' s limitation , such as the poor speed of a / d , d / a conversion and dsp process , the most part of sr system adopt middle course . that is to say , by using the special digital converter or running relevant arithmetic , it converts the radio signal to intermediate frequency signal and completes the base - band signal process that is n ' t the veriest sr and is named " software defined radio ( sdr ) "
由于受到硬件性能如a d 、 d a及dsp芯片处理速度的限制，目前的软件无线电系统多采用折中的实现方案，增加专用的数字变频器或者运行数字变频算法，将射频信号变频到中频，然后再进行基带信号处理，这样的软件无线电系统又被称之为“软件定义无线电” ，它并不是真正意义上的软件无线电。
