一、前言目前,微机已广泛地应用于各个领域。在通信机中应用微机,可以实现智能化。它能自动地控制信道,调节发射功率、检测故障、调节匹配、选呼、跳频通信等等。使通信机的功能自动化,性能越来越好,可靠性不断提高。微机在通信中的应用有着广泛的前景。本文主要论述微机在信道控制中的应用。其重要是用微机控制频率合成器,接收机输入回路,发射机输出回路。实现频道的予置,频率扫描,存贮频道扫描,自动选择无信号干扰信道,使之工作于最佳状态。
I. Introduction At present, microcomputer has been widely used in various fields. Microcomputer used in the communication machine, you can achieve intelligent. It can automatically control the channel, adjust the transmit power, detect faults, adjust the match, select the call, frequency hopping communications and so on. Make the function of communication machine automation, the performance is getting better and better, the reliability is improving constantly. The application of microcomputer in communication has a wide range of prospects. This article mainly discusses the microcomputer in the channel control application. Its important is the use of computer-controlled frequency synthesizer, receiver input circuit, transmitter output circuit. Pre-channel to achieve the frequency scanning, storage channel scanning, automatic selection of signal-free channel interference, so that work in the best condition.
