| 中文摘要: |
| 叙述和介绍了采集交流信号的常用方法，指出了常用方法在采集幅度快速变化的交流小信号时存在的缺陷。在此基础上提出了一种新的交流信号同步采集方法，适合于对采样率和采集精度要求较高的场合。 |
| 英文摘要: |
| This paper produces the method prequently used for acquiring alternating signal, and points out the limitation of acquiring fast changing weak alternating signal. On the base of them, a new synchronous sample method for acquiring signal is presented. With the new method, the high rate and accuracy can be reached. |
