基于LabVIEW的调制器设计与实现

Design and Realization of Modulator Based on LabVIEW

调制是测控通信领域的一个重要概念,是通信系统的基础理论。为了克服传统调制器的局限性,结合调制原理,设计了基于LabVIEW的调制器。并利用LabVIEW软件进行了模拟仿真。仿真结果表明,所设计调制器界面美观、程序简洁。通过波形图和频谱图,形象生动地从时域和频域两个角度展示调制效果。将复杂的公式图形化,将抽象的概念具体化,实现了对信号的可视化调制。

Modulation is an important concept in communication field, and is the basic theory of communica- tion system. In order to overcome the limitation of the traditional modulator, a modulator is designed based on Lab- VIEW combining with the modulation principle. Simulations were done by LabVIEW software. Results shows that, the modulator designed have beautiful interface and concise program, displays modulation effect vividly from the time domain and frequency domain, graphical complicated formulas, and materialize abstract concepts, realize the visualization of modulation signal.
