- Abstract:
- Parameters estimation of a data acquisition system can be performed by using several estimation algorithms. The choice of the most appropriate test method is not straightforward, but it depends on both the type of the converter under test and on the parameters to be measured. Moreover, various test methods and algorithms may present different sensitivities to noise and system parameter’s variations, thus resulting in diverse estimation accuracies. In this paper, the number of effective bits of a commercial 16-bit acquisition system has been evaluated by using a remotely controlled environment based on the network. Experimental data obtained by using the code density and a frequency domain based test techniques are presented and compared with published theoretical results. It is shown that a suitable choice of the procedure parameters allows optimum exploitment of available measurement resources.
