Tytuł: Analysis experimental research data with the help of numerical derivative

Streszczenie: A lot of research data is generated during carrying out experiments like for example in case of oscilloscope records. In this huge amount of information a lot of it is irrelevant. Therefore finding the useful information can be difficult. The influence of closing a short-circuit current with an electromagnetic relay on its contacts was tested. During those tests a large amount of data, recorded by oscilloscope, was created. Only a small portion of this information was useful. The problem was to find specific information in all of the gathered data. This article presents the usage of scientific software designed to solve this issue. It also describes the usage of numerical derivate for finding a specific time range of collected waveforms .

Słowa kluczowe: numerical methods, derivative, electrical contacts
