| Abstract: | The signals to be tested by this sampling system are of little amplitude and short duration.The requirements for design of this sampling system are dealt with in this paper.Based on the frequency and instantaniety theory,the signals to be tested are analyzed,the system is designed and the sampling frequency is determined.The object to be tested,the sampling system and the computer are checked as a whole to meet the design requirement at a low cost. |
