Krzysztof Konopka, Tadeusz Topór-Kaminski
Abstract:
Nowadays measurement data coming from all kinds of measurement systems is usually processed by algorithms. These algorithms are often delivered to the user as complex program and their numerical structure is not known. Therefore also influence of algorithm on an accuracy of processed data is not known. Coefficient matrix of algorithm represents its numerical operations and it can be a basis to algorithm accuracy evaluation. The paper presents a method how to identify this coefficient matrix. As an example this method is used to identify an FFT algorithm implemented in LabVIEW.
