Testing of High-Resolution / Middle-Speed A/D Converters and Modules - Problems and Ways of their Solving
نویسنده
چکیده
The paper describes solutions, how to improve a quality of basic testing methods to be possible to use them for dynamic testing high-resolution / middle speed AD converters and AD modules. The following methods are described: an application of low-distortion band pass filters, a digital correction of a known distortion of a testing signal, an application of a two-tone (or multitone) signal, an application of a non-deterministic signal (noise). The method, which combines a filtration of testing signal and a following digital correction, is described and proposed as the perspective one. The AD transfer standard, which is applied for an evaluation of testing methods and systems is also mentioned.

Abstract: This paper, first it has reviewed the literature on the characteristics of mathematical word problems and their solution process. The review revealed that among the root causes for students’ difficulties with mathematical word problems, two factors are salient, namely the text complexity and the unfamiliar context. To shed more light on these findings, a factorial experimental study w...
