SANTAD is able to display the status of each optical network unit (ONU) connected line on a single computer screen with capability to configure the attenuation and detect the failure simultaneously.

The new scheme utilizes an existing digital foreground calibration algorithm and extends it to work in background. The goal is to digitally calibrate the pipeline ADCs in the background without stopping the input conversion. In this method one additional stage connected in parallel to the stage under calibration and one cyclic ADC are used to accommodate the calibration. The extra stage and the cyclic ADC are only used during the calibration process. Sources of error in pipeline architectures and effects of error on residue plot of 1-bit per stage are identified and discussed. The digital background calibration accounts for capacitor mismatch, comparator offset, charge injection and finite op-amp gain. By applying proposed calibration to a 12 bit resolution pipeline ADC, maximum INL improved from 14 to 0.6 LSB, and maximum DNL improved from 26 to 0.8 LSB.","PeriodicalId":176934,"journal":{"name":"2009 International Conference on Signal Acquisition and Processing","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126238712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach is based on the LSB substitution technique applied on RGB color components of BMP images. The key idea is to divide the image into segments and process them differently. The presented approach considers three algorithms corresponding to three spiral substitution. The proposed algorithms are presented and their performance against attacks and processing time are evaluated. The embedding time was compared for the proposed algorithms as function of the message length up to 20 KB. Numerical experimentation suggests that the embedding time varies linearly with the message length.
