描述了锁定放大器操作的基本原理。特别强调的是在典型测量期间查看锁定各个阶段中存在的信号的频率分量。这里介绍的描述已成功用于向欧柏林学院的高年级实验室学生解释锁定操作。
The basic principles behind the operation of a lock-in amplifier are described. Particular emphasis is placed on looking at the frequency components of the signal present at the various stages of the lock-in during a typical measurement. The description presented here has been used successfully to explain lock-in operation to upper-level laboratory students at Oberlin College.
