Iterative Method and Dithering with Averaging used for Correction of ADC Error
Additive iterative method in combination with averaging of dithered samples is designed for self-correction of ADC linearity error in the paper. Iterative method is one of the automated error correction techniques. Dithering is a special tool for quantizer performance enhancement. Dither theory for Gaussian noise and averaging has been used for exhibition of method abilities in ADC characterist...
متن کاملSelf-Correction of ADC Error Using Additive Iterative Method and Averaging of Dithered Samples
In the paper the combination of additive iterative algorithm with averaging of dithered samples is designed for self-correction of ADC linearity error. Iterative method is known as the aid for automated error correction and dithering uses to be applied for quantiser performance enhancement. Dither theory for Gaussian noise has been used for exhibition of new method abilities in ADC characterist...
متن کاملInterpolation of Microcontroller Adc by Self- Induced Dithering
The resolution of ADCs (Analog-to-Digital Converters) can be improved by dithering, i.e. by intentionally injecting white noise into the analog signal. This work describes the theory behind dithering, how to optimize the magnitude of the noise and also a design that illustrates how dithering can be implemented to increase the resolution of a microcontroller’s ADC. In order to demonstrate the po...
متن کاملImproved Iterative Correction for Distant Spelling Errors
Noisy channel models, widely used in modern spellers, cope with typical misspellings, but do not work well with infrequent and difficult spelling errors. In this paper, we have improved the noisy channel approach by iterative stochastic search for the best correction. The proposed algorithm allowed us to avoid local minima problem and improve the F1 measure by 6.6% on distant spelling errors.
متن کاملIntegral Nonlinearity Correction of Multi-Range ADC by Iterative Applying of Multi-Resistors Divider
The method of testing points generation for identification and correction of integral nonlinearity of high performance ADC is developed. The proposed method is based on averaging all voltages of multi-resistors voltage divider. The main idea of proposed method is in comparison results of analog to digital conversion obtained on different ranges of tested ADC for the same input signals. It is in...
