摘要
本文介绍应用DSP技术对任意波形的产生、实现及输出进行控制,结合Lab Windows/CVI开发软件,设计实现任意波形产生的操作面板。通过在操作面板上选择正弦波、三角波、锯齿波等常用波形以及手工绘制任意波形,经过归整、数/模转换、滤波和放大,实现了波形连续平滑的输出。
This article introduced that using the DSP technology to control arbitrary waveform＇s production, realization and output, with Lab Windows / CVl development software, designed to achieve arbitrary waveform of the operation panel. Through chooses sine wave, triangular wave, rectangular wave ,and other commonly used waveform , arbitrary hand drawing waveform on the operation panel,after consolidation, A/D conversion, filtering and amplifier, the profile＇s continuously smooth output was realized.
