摘要
针对学生在学习"信号处理类"课程中存在的抽象、难理解等问题,打破传统信号处理实验受时间和场地的限制,利用LabVIEW软件具有可视化界面强的特点,制作了简洁美观、可拓展性强的信号处理实验仿真平台,实现了对所有信号处理类课程中涉及实验的计算机仿真,包括初级信号分析、高级信号分析、滤波、频域分析、调制、采样、时域分析、加窗等。实验结果表明:该平台具有实验参数可灵活设置和良好的人机交互功能,并且通过应用程序生成器将该实验平台转化为可执行的EXE文件,该实验平台可以脱离LabVIEW环境,在任何计算机上灵活使用。
Aiming at the existing learning problems of abstract and complication encountered by the undergraduate students, this article breaks the time and space limitation of traditional signal processing experiment, and produces a brief beautiful and expansible signal processing experiment simulation platform, by using the LabVIEW＇s good feature of visual interface. It realizes the experimental computer simulation involving all signal processing kind courses, such as signal analysis, high level signal analysis, filter, frequency-domain analysis, modulation, sample, time-domain analysis, windowing filter, etc. The experimental results show that this platform has the good features of flexible parameter setting and friendly human-computer interaction function. And also, this platform can be changed into executable files by application program builder, so that it can be run on any computer flexibly, breaking away from LabVIEW environment.
