Download or read book Demonstration of the Feasibility of Using Delta Modulation for Pictorial Transmission written by ROBERT V. COTTON and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive investigation of delta modulation techniques for encoding pictorial data was made. The objective was to determine the parameters of delta modulation systems for various image communication applications by (1) system analysis, (2) computer simulation, and (3) experimentation. The analysis of delta modulation techniques includes one-bit and two-bit systems with both linear and exponential integration. Computer simulations of delta modulation logics conducted were (1) one-bit with linear and exponential integration, (2) two-bit with linear and exponential integration, and (3) most importantly, data-link noise with mentioned systems and also pcm. Images of these simulations are presented for evaluation. An experimental two-bit delta modulation encoder with a sampling rate of 50 mc was constructed and tested. A table of the key parameters of pcm and delta modulation systems is presented. Using this table and the images, the image communication system designer can readily choose the best technique and combination of parameters to fulfill his particular application. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An extensive investigation of delta modulation techniques for encoding pictorial data was made to determine the parameters of delta modulation systems for various image communication applica tions by system analysis computer simulation, and experimentation. The analysis and computer sim ulation included one-bit and two-bit systems with linear integration, double linear integra tion with prediction, and exponential integra tion. A feasibility model of a 25-mc two-bit exponential integration delta modulation encoding and decoding system with a serial bit rate of 100 mpps was designed, constructed, and tested. A table of the key parameters of PCM and delta modulation encoding systems, based upon the anal ysis, simulation, and implementation, is present ed. It is concluded that for a typical image communication system, two-bit delta modulation with exponential integration and sampling at two to three times the information bandwidth repre sents the best compromise of parameter. The re sultant compaction over six-bit PCM is two to three.

Book excerpt: Statistical coding and visual fidelity criterion approaches to the television bandwidth reduction problem are described and contrasted. A review of techniques based on both approaches is presented. A brief discussion of television signal properties and several television user applications is included. Emphasis is placed on bandwidth and/or power reduction through consideration and utilization of human visual summation properties. A class of reduced rate systems with random-scanning, noninformation bearing masks, and amplitude weighting are presented and discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Pulse-modulation and integrated circuits, respectively, are the most recent major advances in the communications field and in electronic devices. The evolutionary development of one pulse-modulation technique, Delta Modulation, is examined in this thesis to determine the feasibility of extending its evolution to the inclusion of integrated circuits in its design. An experimental circuit, demonstrating this feasibility, is described and evaluated. (Author).
