积分运算电路实验中的信号调试

Debugging of Integrator Circuit Experimentation

结合积分运算电路实验中出现的现象,介绍了由集成运算放大器构成的积分运算电路的基本理论,分析、解释了某些理论与实测出现矛盾的原因,提出了积分运算电路的改进措施和调试方法,并介绍了一种抑制"漂移"现象的近似积分电路,有效地解决了出现的问题,具有较强的实用性.

The principle of the integrator circuit which is constituted of operational amplifier is introduced. Some phenomena in the integrator circuit experimentation are analyzed. Contradictory appearances of theory and measured one are explained. Improved measures and debug methods are introduced. Specific approximate integration circuit is introduced to depress excursion phenomena. The circuit solves the problems effectively, and thus has strong practicability.
