Delta modulation

View this topic in
Delta modulation (DM or Δ-modulation)is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance. DM is the simplest form of differential pulse-code modulation where the difference between successive samples is encoded into n-bit data streams. (Wikipedia.org)

An Extended TOPSIS for Belief Group Decision Making

Chao Fu; Shanlin Yang; Wenxing Lu Fourth International Conference on Fuzzy Systems and Knowledge Discovery (FSKD 2007), 2007

This paper extends TOPSIS (technique for order preference by similarity to ideal solution) to solve multiple attribute decision analysis (MADA) problems in the situation of belief group decision making (BGDM) where the evaluation of each decision maker (DM) is represented by the bba (basic belief assignment). In the extended TOPSIS, we combine group preferences with the pre-operation of external aggregation, ...


FPGA based sigma-delta analog to digital converter for power sensing

P. Sateesh Kumar; D. Lakshmi Narayana; V. Ravi Tejesvi; M. Kesab Chandrasen 2016 International Conference on Electrical, Electronics, and Optimization Techniques (ICEEOT), 2016

This paper discuss the design and implementation of Sigma-Delta Analog to Digital converter (ΣΔ A/D converter) within an FPGA for a moderate current sensing application. Although FPGA do not posses such analog interface but it is possible to implement an ADC inside an FPGA by taking advantage of the low voltage differential signaling (LVDS) receiver inside the FPGA With a ...


Algorithms for Delayed Encoding in Delta Modulation with Speech-Like Signals

J. Uddenfeldt; L. Zetterberg IEEE Transactions on Communications, 1976

This concise paper is concerned with the problem of improved delta-coding by using delayed decision instead of bit-bit-by-bit decision. It is found that delayed encoding allows a fairly general predictor to be used without causing instability problems. Simulations indicate that considerable improvement can be achieved by matching the feedback filter to the input process. Delayed encoding requires a search algorithm ...


On a delta modulation based real time autocorrelator

Jing Yuan; Jing Ou-Yang ICASSP '85. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1985

Theoretical analysis indicates that the quantization error of a linear delta modulator (LDM) output can be divided into an equivalent PCM quantization error and a high frequency noise irrelevant to the input. Under certain treatment the autocorrelation of a DM output can approximate that of the input signal's derivative. Simulation and experimental results prove that a delta modulation based autocorrelator ...


A multi-digit incremental coding of speech for low bit rate transmission

M. E. M. Nasr; S. A. Khamees Radio Science Conference, 1999. NRSC '99. Proceedings of the Sixteenth National, 1999

An improved waveform coding technique able to produce a good quality of speech in the vicinity of 16 Kb/s is presented. The proposed scheme generates an output code word, which consist of a binary and a ternary digit. This is achieved by modifying the basic step size compared to the other systems, and hence, provide a more accurate reproduction of ...
