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 estimating 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. Using these results, a correction formula is proposed, and its applicability is discussed.

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 estimating 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. Using these results, a correction formula is proposed, and its applicability is discussed.| File | Dimensione | Formato | |
