| 摘 要： | 由双电压频率转换器(VFC)构成高精度色谱数据采集的方法,与常用的由变量程提高分辨率的方法相比,它不存在因信号突变而引起VFC无法快速响应的问题,系统采用双VFC同步工作机制,能在10Hz采样频率下达到2×106的分辨率,具有实施简单、精度高、噪声小、价格低等特点,可广泛应用于各种分析化学信号采集。

| Abstract: | A new chromatographic signal sampling system consisted of two VFCs is proposed in this article. Compared with the conventional sampling method which improves the resolution on the basis of scale changing, this system doesn't have the problem that VFC can't response rapidly with the sudden change of input signal. The system is easy to be constructed and has the properties of high accuracy and low noise. It is cheap in cost and can be applied to the sampling of various analytical chemical signals. |
