The development of cellular communication , multiple addressing and frequency multiplexing techniques , etc . provides a guarantee for leo satellite mobile communication . in order to improve the flexibility of communication systems , we hope that the a / d , d / a converter should be near rf - end , that is , programmable devices can implement the whole processing in middle frequency 为了使得通信系统具有较大的灵活性和可扩展性,我们希望a d 、 d a变换器尽量向射频端靠拢,即完成射频到中频的下变频后,整个中频的处理都用可编程数字器件以及软件来实现。
Under the development of modern industry technology , the applications of digital components are more and more widely . as the base of the information and automation field , the micro - chip is very important . because micro - chip has n ' t the self - development function like pc 随着现代工业技术的发展,单片机, dsp , arm , cpld等数字器件的开发与应用得到了越来越广泛的应用,作为信息化自动化领域的一个分支,单片机起着重要的作用,由于单片机不能象pc机一样具有自开发功能,所以,作为单片机开发工具的仿真器性能的好坏直接影响着单片机开发的效率与性能。
