- Abstract:
- Digital post processing of ADC output data requires among others a fast computational algorithms aimed on the enhancement of ENOB restricted by nonlinearities of the ADC. The paper deals with advantages and disadvantages of implementation Bayesian interpolation theorem to reduce large scale errors in output signal in spite of dithering with high peak-peak voltage. Interpolation process based on Bayesan model smoothes the distortion in the output signal caused by the integral nonlinearity in the ADC transfer characteristic. It suppresses also the random errors generated by allegory errors affecting the analog to digital conversion process.
