the council of areopagus as a judicial establishment monitored the proper implementation of rule of law in the polis (city-state) of athens. while, the main responsibility and duty of areopagus was to adjudicate the cases of the most serious crimes, it intervened in the political affairs as well. eventually, after long-lasting political conflicts between athenian oligarchy and democracy, this e...

The present work describes the implementation of a better convergence adaptive filter through the least mean square algorithm for both sinusoidal and audio denoising i.e., to obtain an original sinusoidal signal and the audio signal back from the same which was corrupted using a random noise .The application had been performed over an FPGA (field-programmable gate arrays) Spartan 3 from Xilinx,...

mobility and portability with high-bandwidth data, voice, and video access. This has led to the introduction of wireless LAN technologies, which attempt to provide exactly that. In the 2.4 GHz frequency band, IEEE 802.11b is “the” wireless LAN solution in the market. However the 5 GHz frequency has two possible contending technologies — IEEE 802.11a and HiperLAN2. This white paper explains the ...

The implementation of digital demodulators using FPGA platform has been presented in this paper. The softwarehardware platform based on Spartan 3A has been developed for digital signal processing purposes .This platform represents the optimal choice from the standpoint of costs, performance and power consumption. The bank of FIR filters is particularly designed for signal analysis applications....

This paper describes a digital realization of a click modulator for a class-D digital audio power amplifier. The click modulator is an interesting alternative to a classical pulse width modulator. The modulator was realized using a floating point digital signal processor ADSP21065L and FPGA circuit Spartan 3 XC3100E. Some simulation and laboratory test results are presented in this paper. Stres...

This work focuses on the image steganography with an image compression using Discrete Wavelet Transform (DWT) on FPGA Spartan III Evaluation Development Kit (EDK). Current trends support digital image files as the cover file to hide another digital file with secret message or data. At receiver side, using Inverse Discrete Wavelet transform, both original image as well as hidden data can be succ...

The role of the Web for text corpus construction is becoming increasingly significant. However, the contribution of the Web is largely confined to building a general virtual corpus or low quality specialised corpora. In this paper, we introduce a new technique called SPARTAN for constructing specialised corpora from the Web by systematically analysing website contents. Our evaluations show that...

This paper proposes a methodology for characterising power consumption of the fine-grain fabric in reconfigurable architectures. It covers active and inactive power as well as advanced low-power modes. A method based on random number generators is adopted for comparing activity modes. We illustrate our approach using four field-programmable gate arrays (FPGAs) that span a range of process techn...
