用计算机代替示波器观测模拟信号波形

On the observation of analog signal wave shapes through the computer

为了实现计算机代替示波器观测模拟信号波形,从A/D转换、抗干扰电路、系统误差处理等方面对其进行了讨论.该方法不仅可以观测模拟信号波形而且还可以储存、分析信号波形,是一种简单、经济、实用的观测方法.

To make sure that we can take the measure to observe analog signal wave shapes through a computer instead of an oscilloscope, the paper was focused on the research into A/D conversion, anti-jamming circuit and processing of problems with systematic errors. The suggested method will help us observe, save, and analyze the analog signal wave shapes, which is simple, economic, and practical.
