摘要
介绍了一种基于MATLAB GUI的虚拟仪器设计方法。系统以手绘波形为信号数据源,通过调用MATLAB DAQ工具控制声卡D/A转换器,实现了声卡在音频范围内任意波形信号的输出。
A method to designing virtual instrument based on MATLAB GUI is introduced.According to its datasource in hand-drawn waveform graph,the designed instrument generates general waveform in audio range by controling the A/D of sound card with MATLAB DAQ.
