Achieving Higher ADC Resolution Using Oversampling
To effectively strike a balance between system cost and accuracy, higher conversion accuracy is achieved by oversampling the low-resolution ADC integrated within a digital signal controller (DSC), and then processing the oversampled digital signal in software through a digital filter and a decimator. This processing scheme, which adds additional bits of accuracy to the 12-bit ADC conversion in ...
متن کاملImage Resolution Enhancement using Multi - wavelet Transforms with Interpolation Technique
Images with high resolution give better results for image processing applications. Image resolution enhancement is the process of manipulating an image so that resultant image is more suitable for specific application such as medical, agricultural, satellite image processing. This paper is based on image resolution enhancement by combination of SWT & DWT .In DWT main loss is on high frequency c...
متن کاملDenoising and Resolution Enhancement of MRI Image using Preprocessing Technique
Quality measure of the data picture to any handling is of most extreme significance as this would help in enhancing the procedure the picture is included in. The preprocessing methods are those which would help the picture to be prepared for any handling. This venture utilizes the preprocessing systems of the picture to go about as a quality analyser of any picture. This work thinks the middle ...
متن کاملResolution Enhancement of PMD Range Maps
Photonic mixer device (PMD) range cameras are becoming popular as an alternative to algorithmic 3D reconstruction but their main drawbacks are low-resolution (LR) and noise. Recently, some interesting works have stressed on resolution enhancement of PMD range data. These works use high-resolution (HR) CCD images or stereo pairs. But such a system requires complex setup and camera calibration. I...
متن کاملIncrease Dynamic Range of Sar Adcs Using Oversampling
In some previous articles general overviews of Δ-Σ and SAR (successive approximation register) ADCs, the techniques of oversampling as it relates to signal-to-noise ratio (SNR) and effective number of bits (ENOB) have been covered. The oversampling technique is most often used with the Δ-Σ ADC, but it is also useful with the SAR ADC. In this article we will dive in a bit deeper to see how this ...
