本文以脉冲系统的观点及离散拉氏变换的方法
研究了开环变参量取样变换系统的过渡特性及各相应典型情况的系统建立时间。从分析的结果得出开环取样变换系统的建立时间t
r
与半功率频宽B有以下确定的关系:t
r
=0.35/B。
The determination of transient response and rise time of the open-loop variable-parameter sampling oscilloscope are studied with the standpoint of "impulse system theory" and by the method of discrete Laplace transform. The conclusion is that the bandwidth and rise time of sampling oscilloscope can be correlated by the simple expression
tr = 0.35/B
though the sampling process is nonlinear.
