Sampling errors are generally believed to dominate the errors of analytical measurement during the entire environmental data acquisition process. Unfortunately, environmental sampling errors are hardly quantified and documented even though analytical errors are frequently yet improperly reported to the third decimal point in environmental analysis. There is a significant discrepancy in directly...

Abstract—This article addresses some implementation challenges in the potentially very energy-efficient chargesampling radios. Alternative ways to implement charge sampler in charge sampling radio are considered, and the impacts and spectral shape characteristics of the sampling jitter induced signal distortion are analytically studied in these cases. The analysis shows that the spectrum of the...
