Abstract :
In this paper, the effects of sampling upon rise-time measurements with a digital oscilloscope are considered. In particular, the use of linear interpolation for the estimation of signal rise times is discussed, and its effects are analyzed for various step signals. A simple expression is derived, which accurately models the sampling and linear-interpolation contributions to the overall rise-time-measurement error. By using these results, a correction formula is proposed, and its applicability is discussed.
