The basic assumptions of ADC effective bits estimation procedures are analyzed in depth, and lower bounds to the achievable accuracy are derived. It is shown that such bounds depend on the ratio between the number of acquired samples of the input sinewave and the number of ADC quantization levels. The effect of broad-band noise superimposed on the input sinewave is also analyzed. Results are provided useful for the design of the estimation procedure itself.

Abstract
The basic assumptions of ADC effective bits estimation procedures are analyzed in depth, and lower bounds to the achievable accuracy are derived. It is shown that such bounds depend on the ratio between the number of acquired samples of the input sinewave and the number of ADC quantization levels. The effect of broad-band noise superimposed on the input sinewave is also analyzed. Results are provided useful for the design of the estimation procedure itself.File in questo prodotto:
