| Abstract: | 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. |
