Abstract : it is well - known that the sampling period of some da ta acquisition syst ems ( das ) , if not short enough , may limit the evaluation of their transient perfo rm ance 文摘:数据采集系统的采样周期是有下限的,即其采集速率不可能无限高,这在实际应用中常常限制了其瞬态响应特性的获得。
Because of that there is a lowest limit of the sampling rates of each data acquisition system , that is the sampling rate can not be at any value ( especially it can " t be at any high enough ) , one can " t get the transient performance of das sometimes , and it may limits the evaluation of their transient performance 由于采样周期是有下限的,即采集速率不可能无限高,这在实际应用中常常限制了其瞬态响应特性的获得,因而也限制了其传递函数的辨识和评价。
