Original Abstract

Input noise estimation of mixed-mode measurements systems requires the knowledge of effective noise bandwidth ENBW and noise density of each component. Determining ENBW is not trivial because each component has a different frequency response. However, it is possible to simplify this problem by only considering the components with the lowest cut-off frequencies. In mixed-mode systems that is usually digital filters. Therefore, if the frequency response of these filters is known, it is possible to determine the ENBW of the entire system. It is then trivial to calculate the effects of individual components on input noise using their noise densities. Experimental verification of the calculation was carried out and both calculated and measured noise values are presented.
