基于LabVIEW语言的模拟调制系统的设计

Design of a LabVIEW-based Analog Modulation System

介绍了利用Lab VIEW语言实现的模拟调制系统的设计。用正弦波作为载波实现幅度调制和频率调制。用Lab VIEW语言实现上述两种模拟调制,并将各系统进行程序管理,生成适合用户使用的界面。采用层次化、模块化的设计方案,利用虚拟仪器技术设计的模拟调制系统,具有直观性,可操作性,调节参数方便等优点,适合用在高校的实验教学中。

A design was proposed on an analog modulation system by means of LabVIEW,wherein a user-friendly interface was generated through procedure management over subsystems after sinusoid was used as carrier wave to modulate amplitude and frequency via LabVIEW.The system,designed with the virtual instrument technology according to a hierarchically modularized program,is applicable to experimental teaching in universities for its high intuitiveness,operability and convenience for parameter adjustment.
