Rao","doi":"10.1109/INCEMIC.2015.8055836","DOIUrl":"https://doi.org/10.1109/INCEMIC.2015.8055836","url":null,"abstract":"EMI / EMC considerations are very important and can't be ignored in modern electronic, electrical and electromechanical systems. The performance of these current day systems is highly influenced by other electronic / electrical / electromechanical systems working around it and vice versa. These systems are either influence or getting influenced by other systems, working in tandem. Many examples are visible around us which are influenced by this unwanted phenomenon, which include cross talk in cell phones or hissy noises in mobile radios, shaking of computers screens during cell phone signal reception etc., which are normally operates over narrow band frequency ranges. Thus many engineers are working very hard to reduce EMI in their systems, while protecting the interests of neighboring systems. Considering these facts, the electrical engineers can estimate the level of EMI in ultra wide band (UWB) systems, which are coming into existence over past many years. As UWB system accepts many MHz / GHz band of signals, EMI is more predominant in these systems and affects the performance of the self and neighboring systems. In practice, Electronic Warfare (EW) systems are collocated with many other electronic, electrical and electromechanical systems like navigational radars, early warning radars, fire control radars, wire & wireless communication systems, sonars, Missile control systems, Gyro systems, CW illuminators, Gun Control Systems, High speed computers, monitors, etc.,. The interoperability of these systems / subsystems is very critical for military applications. Hence an attempt is made to present various EMI / EMC issues and few practical suggestions implemented to overcome these issues in EW systems are presented in this paper.","PeriodicalId":183137,"journal":{"name":"2015 13th International Conference on Electromagnetic Interference and Compatibility (INCEMIC)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128809430","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}

Hence, it is prone for EMI related problems as encountered by any other electronic equipment. As large number of urban population uses these transport services, they need to be operated taking into consideration all safety precautions inclusive of EMI compliance. The EMI related incidence could create a situation wherein lot of people gets stranded or in worst case scenario put lot of lives in danger. In addition to the routine measurements, the measurements relevant to human physiology (passenger wearing a pacemaker in the heart) also needs to be considered. Many EMI incidences have been reported elsewhere in the world. The product specific standard EN 50121-X series is available for which not only the rolling stock needs to be complied for EMI norms but the whole railway system encompassing Traction Sub Stations (TSS), Auxiliary Sub Stations, Beam switch etc. needs to be considered for measurements. Considering the terrain, other noise sources present around and the nature of EUT (always moving), the radiated emission measurement to be conducted for rolling stock is challenging preposition. Due to a very short time of the rolling stock available in front of the receiving antenna for executing a scan for the entire frequency range, various methodology have to be adopted which includes breaking up the band, taking multiple runs, changing the resolution bandwidth or reducing the scan time. In this paper, we are presenting the methodology and results of the radiation emission measurements conducted for Mumbai Monorail, Phase — I project encompassing rolling stock, Traction Sub Station (TSS), Auxiliary Sub Station (ASS) and Beam Switch Assembly. In addition to taking an ambient scan before every measurement, a separate exercise of noise survey for the duration of 6 to 8 hours at all specified locations where radiated emission measurement was planned was also carried out prior to the actual emission measurements. The noise survey was done as per procedure defined in IEEE 273 standard.","PeriodicalId":183137,"journal":{"name":"2015 13th International Conference on Electromagnetic Interference and Compatibility (INCEMIC)","volume":"435 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124245445","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 PCG can record heart sounds, noise and the additional sounds. Since PCG is recording the heart sound, it is important to analyze the clear PCG input signal only. The analyzation of the PCG signal will be consisting of segmenting the signal into S1 and S2 and then compare, whether the PCG is normal or abnormal. In the existing system the wavelet decomposition approach is used to analyze the PCG signal. Features are extracted from a PCG signal in frequency domain to classify signals. In the proposed approach the Feature selection reduces features provided for classification. Coiflet is used for feature extraction, and different feature selection Statistical methods are used. Information Gain (IG), Mutual Information (MI) etc. Feature selection methods are compared using classifiers like kNN, Naïve Bayes, C4.5, and SVMs. In this paper, two methods are used to analyze the PCG and the accuracy of the Information Gain (IG) is improved when compared to Mutual Information (MI).","PeriodicalId":183137,"journal":{"name":"2015 13th International Conference on Electromagnetic Interference and Compatibility (INCEMIC)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115751503","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}

Extending the concepts of transforming the elliptical function based low pass filter into band pass filter. Parametric analysis is carried out to create a generalized approach for the design of specific band pass filter and fine tuning the response by using PSpice simulator. Low pass zeroes are achieved by optimizing the parallel resonance circuit components of the filter and at the same time pass band transmission is achieved by optimizing the series resonance components. Differential band pass filter conversion from single ended version is presented which is required for performance improvement in IF signal processing requirements for communication links like CDMA & OFDM based systems and direct conversion receivers.","PeriodicalId":183137,"journal":{"name":"2015 13th International Conference on Electromagnetic Interference and Compatibility (INCEMIC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122018219","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}
