Digital signal processing

CHAPTER I INTRODUCTION On systems that perform real-time processing of data, performance is often limited by the processing capability of the system [1]. Therefore, in order to judge the efficiency of any system it is very important that we evaluate the performance of the architectures based on which the system is being built. We can also state that we can make a system more efficient and more capable by working upon the algorithm on which the system is being built. The more efficient

the need for methods to process digital signals is more important than ever. Now that I am on the threshold of embarking on a career that will encompass a major part of my adult life, I think it is natural that I veer towards Signal processing. As I look back, I feel that my natural inclination and excellence in mathematics from childhood has led me along this path. Digital Signal processing incorporates the use of mathematics to manipulate an information signal to modify or improve it in some way

CHAPTER 1 INTRODUCTION With advent of modern high-performance signal processing applications, high throughput is in great demand. Digital Signal Processing is perhaps the most important enabling technology behind the last few decade’s communication and multi-media revolutions. Most recent research in the digital signal processing (DSP) area has focused on new techniques that explore parallel processing architectures for solutions to the DSP problems .DSP is used in a numerous real time application

the research of digital signal processing is undergoing rapid development. At present, it has been used in many fields such as communications industry, voice and acoustics applications, radar and image. The processing of the speech signal is one of the key areas of DSP application. So far, it has formed a number of research directions, such as speech analysis, speech enhancement, speech recognition, voice communication, etc.. With the development of IT technology and voice processing technology, people

The proposed research focuses on Delta Sigma based Digital Signal Processing (DSP) circuits on Very Large Scale Integration (VLSI) systems for low-power intelligent sensors -in particular on building systematic tools to study their design principles and fundamental performance limits of energy-efficient low-complexity architectures and on the analysis of their practical advantages and limits. Integrated intelligent sensors has emerged in a wide range of applications including health care, surveil-

VIDEO DENOISING Nowadays digital cameras which is used to capture images and videos are storing it directly in digital form. But this digital data ie. images or videos are corrupted by various types of noises. It may cause due to some disturbances or may be impulse noise. To suppress noise and improve the image performances we use image processing schemes. In this paper they uses Kalman filter to remove the impulse noise. The Kalman filter is digital signal processing based filter. It estimates
