To prove the concept of the narrow notched DMS, the operating on centre frequency of 4.0 GHz is demonstrated and validated through simulation. The DMS structure is embedded in the middle of transmission lines in order to reject any undesired signals which may interfere with any communication systems. The design was simulated based on Roger Duroid RO4350B with a thickness of 0.508 mm and dielectric constant of 3.48. This type of filter is useful in any RF/ microwave communication systems, particularly to eliminate any undesired signals in wideband spectrum. While maintaining its excellent performance, the overall physical and cost reduction can also be achieved using this technique.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132334291","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}

People are becoming are of the importance of indoor air quality. This paper further advances the technology for indoor air quality surveillance by adding an index feature to it. The index feature, accompanied with real-time monitoring system is very useful in giving the real-time alert to the users on the conditions of the current indoor air quality. This index is very handy because human being's ability to detect the changes in the air quality is limited while the changes in the air quality may be rapid. The index helps the users to recognize the conditions of the air instantly by giving four signals, good, normal, unhealthy and hazardous. The index is developed based on the index used in the outside environment but by emphasizing on the internal air quality elements.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124229012","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 negative feedback employs the resistive drain to gate feedback whereas the balanced amplifier incorporates a compact 3dB branch line coupler. Both designs utilized the GaAs transistor, operated by a 5V DC supply and were implemented in a RO4003 PCB. Comparing the performance of the two designs, the balanced amplifier achieved the best RF performance with a stable gain of at least 17.5dB, noise figure lower than 1.03dB, input and output return loss of greater than 11dB and IIP3 of at least 14dBm, which makes it comparable to previously published works.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123698028","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}

Thus, some of the encryption algorithm employed random number generator to produce this type of numbers. This paper describes the process of selecting the most efficient algorithm to represent the hardware RNG for the usage in cryptography. For this purpose, a number of RNG algorithms are selected and analyzed in terms of the sequence's randomness using theoretical simulator analysis. Among of the algorithms, the Inverse Congruential Generator algorithm was chosen based on the analysis as it provides the most high quality random sequence and insensitivity in initial condition. The algorithm was further proceed to the NIST test for non-randomness test and it shown reasonable complexity. The design was proven to be implemented successfully on hardware as it then been designed using Verilog HDL and been simulated and verified using Altera QuartusII 9.0sp2 web edition software. The design utilized 7,711 logic elements of Cyclone EP1C20F400C6.

In this work, the QRS complex is used to calculate heart rate, representing the main component of the ECG signal. In order to achieve a high level of accuracy by the detector, the measured ECG signal must be free of noise. Typically, such noise originates from power line interferences and baseline wandering. To eliminate these noises, the ECG signal must be processed using the signal processing method. The ECG detection process can be divided into a preprocessing stage, which eliminates noise from the raw ECG signal, and the feature extraction stage, which extracts the QRS complex for heart rate calculation. Based on our analysis, the trade-off between complexity and accuracy in ECG signal architecture is important when designing a high-efficiency system.","PeriodicalId":143806,"journal":{"name":"2014 2nd International Conference on Electronic Design (ICED)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125256915","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}
