Abstract

Peculiarities of transient period for infotelecommunication systems in Tatatrstan Republic are considered. Accounting for economic efficiency and state-of-the art in real telecommunication devices a conclusion about necessity of analogue technologies use is made. Conversion of one frequency oscillation into two frequency and two band oscillations is described as the basic method for development of analogue devices and techniques used in infotelecommunication systems. Using two frequency oscillation allows us to create frequency domain LFM-reflectometer with high accuracy of NDE structural monitoring and location of unauthorized access. Use of two band oscillations allows us to create communication lines with reduction of band pass and hence increase of information capacity. Parameters of conversion and their effect on output spectrum composition are discussed. The given method allows us to get spectrum characteristics with high stability of amplitudes and frequencies. That is very important for measuring and for communication systems.

信息通信系统暂态模拟技术

研究了鞑靼斯坦共和国信息通信系统暂态期的特点。考虑到实际通信设备的经济效率和技术水平，得出了使用模拟技术的必要性。将一个频率的振荡转换为两个频率和两个频带的振荡是开发用于信息通信系统的模拟设备和技术的基本方法。利用双频率振荡，我们可以创建具有高精度无损检测结构监测和非授权访问定位的频域lfm反射计。使用两波段振荡使我们能够创建通信线路，减少带通，从而增加信息容量。讨论了转换参数及其对输出频谱组成的影响。所给出的方法使我们能够获得具有高幅值和频率稳定性的频谱特性。这对测量和通信系统非常重要。
