北京理工大学珠海学院 2020 届本科生毕业设计数字调幅技术及应用研究摘 要在信息技术日新月异的当下，各种通信方式与技术进行着飞速的更新迭代。得益于这个大环境，我们几乎每天都可以体验到信息传递过程的效率、安全性以及准确性。通信的目的是实现信息之间安全、准确、快速、有效的相互传递。调制解调技术的快速发展伴随着应用的广泛普及，同时对信号调制技术的要求也越来越严格。本文基于对数字调幅技术及应用研究，对调制与解调的意义及其实现技术进行分析，重点分析数字调幅技术(2ASK)的调制解调原理，深入研究数字调幅的时域、频域以及技术特性，分析数字调幅的实现方法以及在实际中的应用。关键词：数字调幅；2ASK；调制解调北京理工大学珠海学院 2020 届本科生毕业设计Digital AM Technology and Application ResearchAbstractWith the boom of information technology, sundry communication methods and technologies are undergoing rapid update iterations. In such a large environment, we can experience the efficiency, privacy, also accuracy of the information transfer process almost every day. The aim of communication is to realize the safe, accurate, fast and effective transmit among equipment. The rapid development of modulation and demodulation technology is accompanied by the widespread application, and the requirements for the skill of signal modulation are becoming more and more strict. Based on researching for digital AM technology and its application, paper analyzes the significance of modulation, demodulation and its implementation technology, pay attention to the analysis of the modulation and demodulation principle of digital amplitude modulation (2ASK), and deeply studies the time domain, frequency domain and technology of digital AM Characteristics, analysis of the realization method of digital amplitude modulation and how to apply in practice.Keywords: digital amplitude modulation；2ASK；modulation and demodulation北京理工大学珠海学院 2020 届本科...
