摘要
阐述了被测对象是幅值小、持续时间短的瞬态信号这类采样系统的设计难点和要求.在频谱分析和瞬态分析的基础上,分析了被测信号及采样系统的各环节,并合理地确定了采样频率.
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.
