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)

Optimization of an Oversampling Feedback Coder for Signal Processing Chips

Dielacher, F. Solid-State Circuits Conference, 1989. ESSCIRC '89. Proceedings of the 15th European, 1989

This paper describes the design of a special type of oversampling coder, a so called adaptive interpolative delta modulator. This type of coder incorporates most of the known tricks for improving the signal to noise ratio of an oversampling feedback coder. This system provides higher quality of the processable code than other coders. Due to that fact, the oversampling ratio ...


Single magnetic, unity power factor, isolated power converter with ripple free input current

Wei Chen; Lee, F.C. Power Electronics Specialists Conference, 1998. PESC 98 Record. 29th Annual IEEE, 1998

The discontinuous conduction mode (DCM) boost or flyback circuit is a low cost solution to meet power factor correction (PFC) requirements. However, large ripple current in the input side requires a large differential mode (DM) filter inductor. For an offline application, a complete power supply design may also need an isolation transformer, increasing size, weight, cost and power loss. This ...


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.<>


Transfer function design for &Delta;&Sigma; converters

Jantzi, S.; Ouslis, C.; Sedra, A. Circuits and Systems, 1994. ISCAS '94., 1994 IEEE International Symposium on, 1994

A methodology is presented for the design of noise and signal transfer functions for delta-sigma modulators. A computerised optimiser is used to produce maximal noise-shaping, while meeting those constraints necessary to realise a usable modulator. The design of higher-order modulators is possible, as is the design of unique noise-shaping functions such as for bandpass modulators, complex modulators, or modulators with ...


Top-down, constraint driven design: application to sigma-delta modulator

Fellah, Y.; Abouchi, N.; Tixier, T.; Aubert, A.; Labrak, L. Industrial Technology, 2004. IEEE ICIT '04. 2004 IEEE International Conference on, 2004

In order to reduce analog systems development time, in particular sampled ones, we propose in this article a design method based on behavioral modeling. The method uses a hierarchical "top-down" constraints driven approach. To calculate the design constraints, the "programming by flexible constraints CSPf" method is used. Validation of the approach is made on a sensor interface based on a ...
