A method is derived to measure the integral and differential nonlinearity of an ADC using a sinewave with unknown amplitude and offset. The uncertainty of the measurement is also estimated. In a second phase, the integral nonlinearity is analyzed, using Walsh Transforms, to identify the nonlinearity at the bit level of the ADC.
