【Abstract】 According to compare the merit and demerit between sequential sampling and random sampling in high speed data acquiring,a novel equivalent sampling with the technology of time-delay regulating is presented in this paper,which has achieved the technical indicators of equivalent sampling rate of several GSPS and the probability of observing waveform’s specific parts is greatly increased.The principle and implementation of the technology of time-delay regulating,including design schemes,working flow,and the result of experiment are discussed in this thesis in detail.更多还原
