Sampling Jitter and Finite Aperture Time Effects in Wideband Data Acquisition systems

摘要

This paper presents an explicit analysis of the output error powerin wideband sampling systems with finite aperture time in thepresence of sampling jitter. Sampling jit- ter and finite aperturetime affect the ability of wideband sam- pling systems to capturehigh-frequency signals with high preci- sion. Sampling jitter skewsdata acquisition timing points, which causes large errors inhigh-frequency (large slew rate) signal ac- quisition. Finitesampling-window aperture works as a low pass filter, and hence itdegrades the high-frequency performance of sampling systems.
