Type a Evaluation of Uncertainty Due to Systematic Effects in Digital Oscilloscopes
نویسندگان
چکیده
− The paper presents a type A (experimental) evaluation of the uncertainty due to systematic effects. After a brief discussion about the general problem of choosing a proper mathematical representation for systematic effects in the context of uncertainty evaluation, a pragmatic approach, based on the familiar random variable theory and the ISO 5725 norm is proposed. The approach is called “interinstrument experiment”, on the analogy of the “interlaboratory experiment” of the ISO 5725. Preliminary experimental results, relevant to commercial digital oscilloscopes, are presented and discussed.

Modelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...

Background Calls for evidence-informed public health policy, with implicit promises of greater program effectiveness, have intensified recently. The methods to produce such policies are not self-evident, requiring a conciliation of values and norms between policy-makers and evidence producers. In particular, the translation of uncertainty from empirical research findings, particularly issues of...

متن کاملGaussian Jitter-Induced Bias of Sine Wave Amplitude Estimation Using Three-Parameter Sine Fitting
In this paper, the bias on the estimated amplitude, which is caused by Gaussian jitter, is studied in case of the IEEE 1057 standard three-parameter sine-fitting method. Because no analytical study exists, this source of uncertainty is usually not considered. Nowadays, it is becoming more and more important due to the ever increasing sampling rates available in analog-todigital converters (ADCs...
