摘要
提出了锁定放大器原理实验应以掌握相关检测原理为重点 ,以观察、分析相敏检波器的相位特性为主要内容的建议 .阐述了应用实验内容的选取原则 。
This paper mainly discusses lock-in amplifier theory and how to choose the didactical content of its application experiments. It presents that theory experiments should stress on grasping correlation detection theory, and should take observing and analyzing the phase trait of phase-sensitive detector as its main content. It expatiates on the choosing principle of application experiments' content and designs two schemes of application experiments.
