Research ArticleOpen accessEvery word in the titleDesign of Pass Band Filter in Hybrid Architecture Planar/Non-Radiative Dielectric Waveguide Integration TechnologyGharssallah Ali, Harizi HanenProblem statement: The expansion of RF, microwave and millimeter devices has revolutionized today’s ommunication and sensor systems. Low-cost, high-performance and mass producible millimeter wave technologies are vital for commercial broadband systems. Challenging issues are commonly faced in the design of low-loss integrated circuits for example high-Q band pass filter, which the planar technique is fundamentally limited in performance. Approach: In … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 10 Aug 2012 · 7,092 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsDesign of a Symmetrical Microstrip Bandpass Filter for S-Band Frequency RangeMohd Fadzil Ain, Mandeep Singh Jit Singh, Prabhu, Syed Idris Syed HassanA new type of microstrip bandpass filter is presented with a center frequency operation at 2.5GHz which lies in the S-band frequency range. The filter is designed to be much smaller compared to the same type of parallel-coupled bandpass filter. The simulation results are excellent and the filter is suitable for integration within various microwave subsystems. …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,984 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDiscussion around the Scattering Matrix Realization of a Microwave Filter using the Bond Graph Approach and Scattering FormalismHichem Taghouti, Abdelkader MamiProblem statement: Further to research works made previously and which use collectively the scattering formalism and bond graph technique for the modeling of a physical systems often working in high frequencies, we propose, in this article, a comparative study (discussion) for the scattering matrix realization of a high-frequency physical system. Approach: This discussion is based, on the one hand, on … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 7 Feb 2012 · 7,188 accessesView PDF Cite

Research ArticleOpen accessIn the abstractClassifying Single Trail Electroencephalogram Using Gaussian Smoothened Fast Hartley Transform for Brain Computer Interface during Motor ImageryV. B. Deepa, P. Thangaraj, S. ChitraProblem statement: Brain-Computer Interface (BCI) is a emerging research area which translates the brain signals for any motor related actions into computer understandable signals by capturing the signal, processing the signal and classifying the motor imagery. This area of work finds various applications in neuroprosthetics. Mental activity leads to changes of electrophysiological signals like the Electroencephalogram (EEG) or Electrocorticogram (ECoG). … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,658 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRadiometric Correction of Multitemporal Satellite ImagerySeema Gore Biday, Udhav BhosleProblem statement: Repeated observation of a given area over time yields potential for many forms of change detection analysis. These repeated observations are confounded in terms of radiometric consistency due to changes in sensor calibration over time, differences in illumination, observation angles and variation in atmospheric effects. Also major problem with satellite images is that regions below clouds are not … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 8,393 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Novel High Stop Band All Complementary MOSFET Switched-Capacitor FilterMoussa Abdallah, Ismail NabhanProblem statement: Filters are widely used in various applications including communications, electronics and biomedical engineering. The performance and size of the filter is of interest especially in chip implementation. A switched-capacitor low-pass filter was designed and simulated using a 0.18 μm 1P6M CMOS technology. Approach: This circuit design offered obvious advantages in increasing the stopband attenuation, reducing passband ripple and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,863 accessesView PDF Cite
