On the other hand, such low-cost instruments have a lower sampling rate than the pixel clock in VDUs; pixel information is lost in the image reconstructed from the measured EM waves, and the quality of the image is also degraded. In this letter, we propose a novel method to reconstruct high-quality images from lower sampling rate observations by a nonnegative linear optimization. Our method can recover clear images even when measuring EM leakage at low sampling rates and fluctuating sampling clocks. To obtain a stable and plausible solution to the optimization problem, we focus on fluctuations in sample points caused by clock jitter in devices and instruments and use pixel information obtained by observing multiple frames. To verify the proposed method, we generated simulated data from leaked EM waves, including screen information, and evaluated the visibility of the reconstructed images. Consequently, the images reconstructed using the proposed method were of the same quality as those reconstructed by applying conventional methods to data measured at a high sampling rate sufficient for information recovery. Moreover, we confirmed that even if the image quality is degraded by a decrease in the signal-to-noise ratio of the observed signal and an increase in the clock jitter, the proposed method can still be used to obtain high-quality reconstructed images by increasing the number of observed frames.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 3","pages":"87-91"},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/iel7/8566057/10260712/10201909.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67868215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PQ issues are a subset of electromagnetic compatibility (EMC), and identifying them can help track down problems in large networks. Commercial-off-the-shelf (COTS) sensors range from cheap smart plugs, with limited functionality and accuracy, to high-end measurement devices. For large-scale deployment and future research, a cost-effective solution is needed for distributed measurements. This letter discusses designing and evaluating a cost-effective PQ sensor that fits the gap between cheap smart plugs and high-end measurement devices. It is designed with expandability in mind while keeping the cost down. This allows the device to log other EMI parameters in the future by adding sensors without redesigning the device. An energy measurement accuracy of smaller than 1% is achieved, comparable to a class B energy meter of the EN-50470 standard. It can measure all the elementary electrical parameters so deviations to the EN-50160 can be logged in a (sub)second scale.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 4","pages":"131-136"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76876609","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 following tasks were decided: comparing world power traction systems of railways and their automatics devices, estimating EMIs in the return traction current, and making conclusions for the future. The sources of external EMIs in the automatics and telecommunication circuits are very diverse: traction networks with harmonics and pulses, high-voltage power lines; lightning discharges, which have both dangerous and interfering effects under various conditions; and various industrial sources of electromagnetic fields (motors, generators, and welding units).","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 3","pages":"67-71"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67867182","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}

We observed that designing an FPC for LCD TV modules that can minimize insertion loss (IL) and crosstalk in the channel is critical to successfully implementing multi-Gb/s signal characteristics in large-size and high-resolution LCD TV modules. To prove this experimentally, we investigated the trends of IL, impedance, and crosstalk, which are design parameters of simulation-based FPCs, and designed four FPC samples assuming their application to the intrapanel interface module of a real 75-in LCD TV. Then, based on the measured S-parameter model, the SI performance was verified and compared by measurement and simulation to demonstrate the validity of the proposed design guidelines. In conclusion, to achieve the SI characteristics of FPCs in LCD TV modules, it is necessary to consider minimizing IL and mitigating crosstalk more than any other electrical performance by enabling the differential P/N pairs to have a strong coupling relationship.","PeriodicalId":100625,"journal":{"name":"IEEE Letters on Electromagnetic Compatibility Practice and Applications","volume":"5 3","pages":"97-101"},"PeriodicalIF":0.0,"publicationDate":"2023-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67868216","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}
