介绍了一种用DDS和∑△技术实现用于数据通信的正弦波产生及调制技术的基本思想,给出了实现TSK,PSK和AM调制的方案.这些方案主要由数字电路实现,具有很大的灵活性并可由VLS1技术实现单片集成,可与其它方法如专用可编程处理器(ASPP)和专用信号处理器(ASSP)竞争.
A basic idea of using DDS and ΣΔ to realize the sine wave generation and modulation technology for data communication is introduced and the schemes to realize the TSK, PSK and AM modulation are given.These schemes are mainly realized by the digital circuit and have a large Flexibility and is monolithically integrated with VLS1 technology to compete with other methods such as Application Specific Processors (ASPP) and Application Specific Signal Processors (ASSPs).
