Book excerpt: New results are presented offering insight into the performance and optimization of linear and adaptive delta modulation, together with a comparison with pulse code modulation. The results are applied to three cases of practical importance: television, speech, and broad- band signals. The results presented can be grouped into the following three categories. First, a performance characterization of linear delta modulation (DM) is given. With the aid of certain empirical observations made from computer simulations, closed form expressions are found for granular noise, overload noise, and minimum quantization noise powers. These results per- mit the prediction of the optimum performance obtainable from DM at various bandwidth expansion factor values for many classes of signals. A defined quantity called the slope loading factor is usefully employed in the char- acterization of DM performance. It is shown that the slope loading factor is a normalizing variable when used to describe S/NQ performance. The optimum perform- ance of DM with signals such as television and speech having an integrated spectrum exceeds that with a broad- band signal having a uniform spectrum. It was also foundthat DM performance obtained with a Gaussian message signal amplitude probability density is essentially the same as that obtained with an exponential density. Second, the advantages to be gained when adaptive control is introduced into the DM system are investigated. If the message signal ensemble is nonstationary, a companding function is required. It is shown that this may be provided in a DM system by forcing the step size to respond adaptively to changes in the derivative of the input signal. Adaptive DM may take either a discrete or continuous form. It is shown that discrete adaptive DM does not sacrifice optimum linear DM performance to achieve companding, and further that large values of companding improvement are possible. Because of the nonstationary nature of television and speech signals, it is concluded that adaptive DM appears better suited than linear DM to such signals. Finally, linear DM is shown to be a special case of discrete adaptive DM. Third, the noise performance of PCM with Gaussian and exponential signal densities is presented together with a comparison between DM and PCM for television, speech, and broadband message signals. It is shown that the characteristic form of the performances of PCM and DM are similar when the independent variables are the amplitude loading factor and slope loading factor respectively. The effects of logarithmic companding and signal amplitude limiting on PCM performance are investigated. It has been found that adaptive DM appears capable of realizing a larger companding improvement than PCM, and that amplitude limiting in PCM is the counterpart of slope limiting in DM. For a television signal, it is concluded that DM provides a greater maximum S/NQ performance than PCM for values of the bandwidth expansion factor less than eight. For a speech signal, it is concluded that the performance of discrete adaptive DM with a bandwidth expansion factor value of four and a final gain factor value of only eight is approximately the same as that of companded PCM with a compression parameter value of one hundred. For a broadband signal, it is concluded that the performance of PCM is superior to that of DM. Finally, because of the complex nature of television and speech communication, it is concluded that subjective tests are needed before further conclusions regarding the performance advantages of discrete adaptive DM can be reached. For an abridgment of the material in this dissertation, the reader is referred to a paper of the same title, written by the author, appearing in the Proceedings of the IEEE, March, 1967.

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).
