摘      要：The goal of this paper is to point out the differences between jitter ( the perturbations in sampling points reading) and the measurement errors. In some cases jitter may have significantly smaller influence on the radius of information than the measurement error. The class of Lipschitz functions is considered and two problems, integration and approximation, are studied.
