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)

A fourth-order bandpass Δ-Σ modulator using second-order bandpass noise-shaping dynamic element matching

Ueno, T.; Yasuda, A.; Yamaji, T.; Itakura, T. Solid-State Circuits, IEEE Journal of, 2002

This paper describes a multibit bandpass ΔΣ modulator (DSM) for a frequency- interleaved analog-to-digital (A/D) converter (ADC). A frequency-interleaved ADC using low oversampling ratio (OSR) DSMs is an attractive approach for broadband and high resolution A/D conversion. A multibit DSM is suitable for low-oversampling operation; however, the overall resolution of a multibit DSM is restricted by the accuracy of the ...


An improved achievable region for the discrete memoryless two-user multiple-access channel with noiseless feedback

Bross, S.I.; Lapidoth, A. Information Theory, IEEE Transactions on, 2005

An achievable region for the two-user discrete memoryless multiple-access channel (DMMAC) with noiseless feedback is proposed. The proposed region includes the Cover-Leung region, with the inclusion being, for some channels, strict. This inner bound is demonstrated for the ideal two-user Poisson multiple-access channel with noiseless feedback, in which case it is shown to improve on the Cover-Leung rate-sum.


System-on-a-chip design methodologies and issues for transducer-to-pico-network applications

Fisher, J.S.; Henz, R.; Devarajan, D.; Abele, J.; Bibyk, S.B. Circuits and Systems, 2001. MWSCAS 2001. Proceedings of the 44th IEEE 2001 Midwest Symposium on, 2001

The unique phenomenology of transducers complicates designing the interface of the transducer-to-pico-network protocol. This paper will explore the methodologies and issues involved in the design flow of a mixed-signal microchip through a sensor-to-pico-network design example that has been fabricated in the AMI 0.5 μm process. The design methodologies include a careful decomposition between the digital and analog sections, as well ...


Estimating the intrinsic dimensionality of discrete utterances

Baydal, E.; Andreu, G.; Vidal, E. Acoustics, Speech and Signal Processing, IEEE Transactions on, 1989

The intrinsic dimensionally (ID) of different sets of isolated word utterances is estimated through a method recently proposed by K.W. Pettis et al. (1979). This results show ID values ranging from 3 to 15, which are consistent with the intuitive degree of difficulty associated to the sets considered. Also, some speculative applications of ID estimating are discussed.<>


A 1-V 10-MHz clock-rate 13-bit CMOS &Delta;&Sigma; modulator using unity-gain-reset op amps

Keskin, M.; Un-Ku Moon; Temes, G.C. Solid-State Circuits, IEEE Journal of, 2002

The problem of low-voltage operation of switched-capacitor circuits is discussed, and several solutions based on using unity-gain-reset of the opamps are proposed. Due to the feedback structure, the opamps do not need to be switched off during the reset phase of the operation, and hence can be clocked at a high rate. A low-voltage ΔΣ modulator, incorporating pseudodifferential unity-gain-reset opamps, ...
