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 Advanced Simple Configuration Delta-Sigma Modulation Three-Phase Inverter Implementing Space Voltage Vector Approach

Hirota, A.; Saha, B.; Sang-Pil Mun; Nakaoka, M. Power Electronics Specialists Conference, 2007. PESC 2007. IEEE, 2007

To miniaturize and enhance the performance of a variety type of switching mode inverters and converters, researchers have developed with great efforts so far. In these switching node converters, pulse width modulation (PWM) technique is commonly made use of voltage regulation. In case of using PWM processing scheme, noise peaks appear at the whole number of carrier frequency. And this ...

Optical and electrical characterization of GaAs-based high-speed and high-sensitivity delta-doped resonant cavity-enhanced HMSM photodetector

Chen, Xiying; Nabet, B.; Xia Zhao; Hung-Jen Huang; Cola, A.; Quaranta, F.; Taurino, A.; Currie, Marc Electron Devices, IEEE Transactions on, 2005

We have previously reported an AlGaAs-GaAs-based delta modulation doped resonant cavity-enhanced, heterostructure metal-semiconductor-metal (HMSM) photodetector design with wavelength selectivity, high sensitivity, and high- speed properties. In this paper, the influences of the resonant cavity and the delta modulation-doped layer on the optical and electrical performances of HMSM photodetectors have been studied by using the transmission line model and Ramo's theorem, ...


Use of Sliding-Mode Modulation in Switch-Mode Power Amplification

Shiang-Hwua Yu; Ming-Hung Tseng Industrial Electronics, IEEE Transactions on, 2008

This paper presents a recently developed feedback modulation scheme called sliding-mode modulation. Sliding-mode modulation, operating in sliding mode, simultaneously minimizes the accumulated quantization error and in-band modulation error while converting a continuous input signal into a coarsely quantized signal. With these minimization mechanisms, the modulator exhibits simple tractable behavior in the sliding mode and high in-band linearity in signal conversion. ...


Performance analysis of three-phase inverters controlled by synchronous delta-modulation systems

Mertens, A. Industry Applications, IEEE Transactions on, 1994

Synchronous delta-modulation systems are used to control resonant voltage link inverters, where switching has to be synchronized with the zero crossings of the link voltage. This paper shows that output current harmonic distortion and average switching frequency of such systems can be calculated analytically in spite of the quasistochastic behavior of the modulators output. Under the assumption of constant link ...
