基于DSP技术的长时间积分器

A Long-pulse Integrator based on DSP Technology

本文通过讨论积分器实现的形式和积分误差抑制的措施,介绍了一种先由模拟积分电路对输入信号进行交替积分,再用数字信号处理方式实现积分误差修正和积分结果拼接的长时间、低漂移积分器的设计方法,并给出了相关实验结果。

After discussing the forms and error-suppression of integrator, this article introduces a method to design a long：pulse low-drift integrator, which uses analog circuit to integrate import signals, and then processes errors of analog integrators digitally. At last, the article gives the relevant experimental result of this instrument.
