Two operational transconductor amplifiers (OTA) are used in a mirrored cascade structure. This structure offers a flexible common mode range. The band pass filter uses two OTAs and two capacitors. The structure offers a variable center frequency and variable Q. These center frequency and the Q values can be changed by keeping one capacitor fixed and by varying the second one. The value of the two capacitors is varied to obtain different bandwidths and center frequencies. The theoretical and the simulation result match closely.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126662071","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}

For some arrhythmias that can cause sudden cardiac arrest, the patient needs to be sent to the hospital for immediate treatment. Most of the current electrocardiogram (ECG) devices are bulky, cost expensive, and does not include the self-classification or interpretation ability. Hence it is not suitable for small clinics and patients to use as the first screening devices. This paper proposed a SoC-based implementation of arrhythmia detector by using embedded software design. It able to analyze the heart rate variability (HRV), diagnose and classify the arrhythmias in terms of ventricular fibrillation (VF), premature ventricular contraction (PVC), and two degree heart block (2o Block) base on the R-R interval properties. The ECG signal is pre-processed and extract the R peak using Pan and Tompkins algorithm. The arrhythmia can be detected based on knowledge-based classification of the R-R intervals. The proposed system is prototyped on the Altera Video and Embedded Evaluation Kit with Multi-Touch (VEEK-MT) FPGA development board. Results shows that the proposed system able to classify the aforementioned arrhythmia types with convincing average detection accuracy in range of 85.71% to 93.61% based on MIT-BIH database.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"61 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129532284","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}

However, most previous approaches do not lead to good results. If the density of noise increases rapidly, the quality of the image tremendously decreases and the restoration of those images is a difficult task. This paper proposes an optimal method to suppress the noise with high density properly based on a nonlinear filter and decision-based approach. We assume a 3×3 fix window to scan the image from top-left to bottom-right of the image pixel by pixel. This size of window guarantees the image saving with more details and avoiding the image blurring. There are two steps, detection of the corrupted pixels and then restoration. Detection is provided by using statistical analysis in each window, then the appropriate replacement for the noisy pixel is conducted from given values inside the current window or adjacent reconstructed pixels based on mean calculation and also, for very high density of noise which density of noise is bigger than %80, the reconstruction is based on a recursive approach. Experimental results on some benchmark images and video clips show that this method is a successful algorithm for suppression of salt and pepper noise with high density; besides, they show that the computational complexity and time consuming are reasonable.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128428171","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}
