Enhanced Data For Global Evolution (EDGE)

Today’s fast growing world needs fast communication ,either it may be voice or data. This calls for a new technology which is faster than all existing technologies in mobile communication and hence can replace technologies like GPRS. Enhanced Data for Global Evolution(EDGE) is such a technology .EDGE is a member of global system for mobile communications(GSM). In short EDGE is a technology  which enhances data rates for mobile communications.

Echo Cancellation In Voice Over IP

This paper provides an introduction into the basics of echo cancellation. The paper is kept general but it emphasizes on the emerging Voice over IP (VoIP) market. However, most aspects can also applied to Asynchronous Transfer Mode (ATM) or wireless networks. This paper shows why and where echo cancellation is required, what echo is, and what causes it. It also gives an overview of the standards involved in echo cancellation. The digital echo canceller, meets the requirements of the VoIP market. This paper shows how it can be integrated into a VoIP system and the advantages the solution offers.

Telephone Conversation Recorder

Basically the circuit consists of  a bridge network which is used to ensures that transistor T1 gets voltage of proper polarity, irrespective of the polarity of the telephone lines. To this bridge circuit the telephone line is connected.Resistors R1 and R2 act as a voltage divider. The voltage appearing across R2 is fed to The ‘MIC-IN’ socket of the tape recorder. The second part of the circuit which consists of  two transistors T1 and T2 that controls relay RL1, which is used to switch on/off the Tape recorder. The tape recorder should be in recording mode. The values of R1 And R2 depends on input impedance of the tape recorder’s  MIC-IN  terminals.

Machine Visualization of Synoptic Topography by DSP

The field of digital image processing has experienced continuous and significant expansion in recent years. The usefulness of this technology is apparent in many different disciplines covering medicine through remote sensing. The advances and wide availability of image processing hardware has further enhanced the usefulness of image processing. The broad areas of Application of Digital Image Processing include Medical applications, restorations and enhancements, image transmission and coding, color processing, remote sensing, robot vision, hybrid techniques, facsimile, pattern recognition, registration techniques, multidimensional image processing, image processing architectures and workstations, video processing programmable DSP's for video coding, high-resolution display, high-quality color representation, super high definition image processing.

Wavelet Based Image Compression using Subband Threshold

Wavelet based image compression has been a focus of research in recent days. In this paper, we propose a compression technique based on modification of original EZW coding. In this lossy technique, we try to discard less significant information in the image data in order to achieve further compression with minimal effect on output image quality. The algorithm calculates weight of each subband and finds the subband with minimum weight in every level. This minimum weight subband in each level, that contributes least effect during image reconstruction, undergoes a threshold process to eliminate low-valued data in it. Zerotree coding is done next on the resultant output for compression. Different values of threshold were applied during experiment to see the effect on compression ratio and reconstructed image quality. The proposed method results in further increase in compression ratio with negligible loss in image quality.

Digital Signal Processing in the field of test and measurement

This paper deals with the continuous development of digital signal processing in the field of test and measurement. Continuous  process of development of filters to meet he challenges of bandwidth and accuracy. The real time oscilloscope has been the mainstay of electronic and R&D applications. DSP is a well established discipline. It  has become the enabling toll to extend the oscilloscope bandwidth beyond the current analogue limits and to improve the overall measurement accuracy. This above said extension in bandwidth of oscilloscope is made to reality with the help of filtering technique. In addition, the various developments in digital filters in the field of digital signal processing is discussed.

Chromosome Image Enhancement

Image processing has been used in almost all the areas such as remote sensing, military, biomedical, industrial applications. The world is growing more crowded all the time, with a fragile environment that needs protection. Natural resources are becoming increasingly precious and hard to find. This paper is mainly focused on chromosome image enhancement and future extraction based on karyotyping. The features computed and used for analysis include: centromeric index, chromosome size and banding pattern features including total number of bands. A method that is discussed is enhance the image by applying filtering technique and finds the future of centromere detection. This paper is covered the procedure of enhancement and detection of centromere and presented some of results. The results are obtained by different algorithms using MATLAB. 

Cache Compression

Code compression could lead to less overall system die area and therefore less cost. This is significant in the embedded system field where cost is very sensitive. In most of the recent approaches for code compression, only instruction ROM is compressed. Decompression is done between the cache and memory, and instruction cache is kept uncompressed. Additional saving could be achieved if the decompression unit is moved to between CPU and cache, and keeps the instruction cache compressed as well. In this paper, we explored the issues for compressing the instruction cache. In the process, we discuss a high level implementation for a 64-bit, 5-stage pipeline MIPS like processor with compressed instruction cache.

Bluetooth

During the past two decades, the advancement in microelectronics and VLSI technology dipped down the cost of many consumer electronic products to a level, which was affordable for the common man. The sale of cellular phones is predicted to reach 1 billion in 2005. With increase in the number of electronic devices, comes in the need of connecting them together for maximum interoperability and utilization. Bluetooth is a technology devised to replace the cables.

Biochips

“Biochips”-The most exciting future technology is an outcome of the fields of Computer science, Electronics & Biology. Its a new type of bio-security device to accurately track information regarding what a person is doing, and who is to accurately track information regarding what he is doing, and who is actually doing it. It’s no more required with biochips the good old idea of remembering  pesky PINs, Passwords, & Social security numbers .No more matters of carrying medical records to a hospital, No more cash/credit card carrying to the market place; everything goes embedded in the chip. Every thing goes digitalized. No more hawker tricks on the internet. Biochip has a variety technique for secured E-money transactions on the net. The power of biochips exists in capability of locating lost children, downed soldiers, and wandering Alzheimer patients.
