EDINBURGH NAPIER UNIVERSITY
ANKESH DANDEKAR- 40053303

ABSTRACT: Paper shows the Design, Implementation and Simulation for CLOCK RECOVERY SYSTEM IN DATA COMMUNICATION using Digital Signal Processing technique (DSP) for use in 9.6kbit modems system. This implemented system helps to retrieve the clock from the received data at receiver as the generated clock has same phase and frequency at transmitter. And that recovered clock decodes the data correctly and also provides power saving facility in low serial data communication.
Circuit design and its simulation is fulfilled using MATLAB/SIMULINK, report focuses each and every parameters in design at MATLAB.

...rough rule of thumb, and assuming powers of 2 for convenience, images of size 256*256 pixels and 64 gray levels are about the smallest images that can be expected to be reasonably free of objectionable sampling checkerboards and false contouring. I The results in Examples 2.2 and 2.3 illustrate the effects produced on image quality by varying N and k independently. However, these results only partially answer the question of how varying N and k affect images because we have not considered yet any relationships that might exist between these two parameters. An early study by Huang [1965] attempted to quantify experimentally the effects on image quality produced by varying N and k simultaneously. The experiment consisted of a set of subjective tests. Images similar to those shown in Fig. 2.22 were used.The woman’s face is representative of an image with relatively little detail; the picture of the cameraman contains an intermediate amount of detail; and the crowd picture contains, by comparison, a large amount of detail. Sets of these three types of images were generated by varying N and k, and observers were then asked to rank them according to their subjective quality. Results were summarized in the form of so-called isopreference curves in the Nk-plane (Fig. 2.23 shows average isopreference curves representative of curves corresponding to the images shown in Fig. 2.22). Each point in the Nk-plane represents an image having values of N and k equal to the coordinates of that......

Stewart 1998 2 The DSPedia DSPedia An A-Z of Digital Signal Processing This text aims to present relevant, accurate and readable definitions of common and not so common terms, algorithms, techniques and information related to DSP technology and applications. It is hoped that the information presented will complement the formal teachings of the many excellent DSP textbooks available and bridge the gaps that often exist between advanced DSP texts and introductory DSP. While some of the entries are particularly detailed, most often in cases where the concept, application or term is particularly important in DSP, you will find that other terms are short, and perhaps even dismissive when it is considered that the term is not directly relevant to DSP or would not benefit from an extensive description. There are 4 key sections to the text: • • • • DSP terms A-Z Common Numbers associated with DSP Acronyms References page 1 page 427 page 435 page 443......

...IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS, VOL. 54, NO. 6, DECEMBER 2007 3057 A DSP-Based Remote Control Laboratory Darko Hercog, Student Member, IEEE, Bojan Gergiˇ , Member, IEEE, c Suzana Uran, Member, IEEE, and Karel Jezernik, Senior Member, IEEE Abstract—This paper presents a framework for rapid remote experiment implementation in the field of automatic control. The proposed solution is based on in-house developed embedded control hardware and two commercially available software packages. MATLAB/Simulink is used for rapid experiment control algorithm development, while LabVIEW is used for the user front-end and remote control. A combination of presented hardware and software solutions enables the rapid and easy creation of different interactive remote control experiments. Using this solution, a digital-signal-processor-based remote control laboratory for teaching purposes has been realized. This remote laboratory enables the remote users to easily interact with a set of physical control experiments through the Internet. In the friendly user interface, the remote user can change predefined system parameters and observe system response in textual, graphical, or video format. In addition, this remote laboratory includes a booking system, which enables remote users to book experiments in advance. Index Terms—Automatic control, booking system, dc motors, digital signal processor (DSP), embedded systems, engineering education, LabVIEW, MATLAB, real-time workshop......

...manager device. The call manager devices are more robust than the software versions. The TCNs and JGNs each have two Call Manager devices and support calls over both NIPR and SIPR. With less call volume, PoPs and SNEs use call management software that resides on a server. The JGN interfaces external networks for call relaying. The JGN is equipped with a STANAG 4578 (Standardization Agreement), which ensures interoperability with Allied North Atlantic Treaty Organization (NATO) forces. The VWP supports a SIPR IP phone using TCN voice services. 0003-5 TB 11-5800-229-10 000 3 Analog Gateway. Analog calls from traditional phones are handled through devices called analog gateways. The gateways have Digital Signal processors (DSP) that convert analog voice into IP packets. The packets are then routed across the network in the same manner as is digital data. Analog gateways provide 24 traditional RJ11 phone jacks that support traditional 2-wire analog phones. All user access cases are equipped with analog gateway devices. Call Managers. The Call Manager CUM (CME) software application, runs on a server in the PoP and SNE. The software is responsible for managing call-processing including managing VoIP devices, providing call control, processing, and signaling. It provides a set of calling features, capabilities, and dial-plan administration. The PoP and SNE support SIPR voice calls only. The Cisco Call Manager device supports digital voice and acts as an IP......
