This paper gives an overview of cryptographically strong mass application invisibility in digital communication. It summarizes principles and methodology, clariies terminology, and deenes some new concepts. A new algorithm for hiding bit selection in digital images is proposed and an experimental implementation of the algorithm is described. Finally, the paper closes with a discussion of the im...

Usage of the benefits of electrical communication has become an inseparable part of our lives now. Through this paper, I have tried to summarize various technologies that are important in the field of digital communication and have also included the recent advancements in the same field. The paper starts with the basic idea about the communication system followed by basic modulation techniques ...

These exercises are intended to cover all the main points of understanding in the lecture course. There are roughly 112 questions per lecture, and each question is supposed to take roughly the same amount of time to complete. Don’t expect to be able to answer everything. You are advised not to spend more than an hour on any one question – unless you really want to. Unlike most Tripos questions,...

applications are mobile communication terminals, digital consumer equipment, and multimedia systems. One example of digital consumer equipment is the digital still camera. Hitachi has developed a digital camera system based on the SH-DSP (Fig. 1). ABSTRACT: Recently sales have grown markedly in the field of mobile communication terminals such as global system for mobile communications (GSM), pe...

purpose – this paper aims to describe the role of public libraries in bridging the digital divide. the paper firstly reviews the existing literature body in this area and then suggests a number of practical solutions. digital divide is a concept which appears in the area of information and communication technology (ict) since 1990 and refers to the existing inequality in accessing to ict among ...

Internet application in China has maintained a constant development tendency in the past decade. China is now one of the most populous countries in terms of internet user population. While offering enormous opportunities, the dramatic digitalization also brings about a series of challenges that demand urgent attention. Digital divide is one of the challenges that affect China as well as other c...

This project presents the simulation results of digital modulation schemes BASK,BPSK and BFSK. In long distance transmission digital communication is more efficient and secure. In digital communication part noise detection and correction is very simple than analog communication. Digital modulation represents the transfer of digital bit stream from the transmitter to the receiver via the analog ...

The dynamic design of graphic language can be seen everywhere in life as the digital media era progresses. Graphic designs, such product packaging, poster design, book binding and logo are examples traditional visual design. print is most important factor. that aided by technology not limited to but also includes network media. teaching research China’s specialty still its early stages, relevan...
