数字调幅技术及应用研究

北京理工大学珠海学院2020届本料生毕业设计Digital AM Technology and Application ResearchAbstractWith the boom of information technology,sundry communication methods andtechnologies are undergoing rapid update iterations.In such a large environment,wecan experience the efficiency,privacy,also accuracy of the information transferprocess almost every day.The aim of communication is to realize the safe,accurate,fast and effective transmit among equipment.The rapid development of modulationand demodulation technology is accompanied by the widespread application,and therequirements for the skill of signal modulation are becoming more and more strict.Based on researching for digital AM technology and its application,paper analyzesthe significance of modulation,demodulation and its implementation technology,pay attention to the analysis of the modulation and demodulation principle of digitalamplitude modulation (2ASK),and deeply studies the time domain,frequencydomain and technology of digital AM Characteristics,analysis of the realizationmethod of digital amplitude modulation and how to apply in practice.Keywords:digital amplitude modulation:2ASK:modulation and demodulation
