NONLINEARITIES, THE GENERATORS PERSPECTIVE IN ADC STATISTICAL TESTING TECHNIQUES

Raul Carneiro Martins, António Cruz Serra

Abstract

In this paper we present an experimental method that is suitable to ascertain the degree of nonlinearity present in a given signal as well as its adequacy to be used as a stimulus signal in a statistical method, such as the histogram test of ADCs. We show one possible implementation of the method as well as its theoretical substrate and some preliminary experimental results. Finally we show the importance of determining the distribution of the stimulus signal when using noise.
