Digital recording

View this topic in
In digital recording, the analog signal of video or sound is converted into a stream of discrete numbers, representing the changes in chroma and luminance values (video) or air pressure through time, thus making an abstract template for the original sound or moving image. Beginning in the 1980s, music that was recorded, mixed and mastered digitally was often labelled using the SPARS code to describe which processes were analog and which were digital.

Servo-Burst Radial Period Optimization

Ara Patapoutian; Mourad Benakli IEEE Transactions on Magnetics, 2007

We propose a performance metric to evaluate various servo-burst strategies. This metric generalizes a previous approach and enables the determination of the optimal servo-burst radial period. The results can be applied to servo- burst formats that can be projected on a two-dimensional signal space, including the quadrature servo-burst format. Here, we consider two estimators that trade complexity with performance


Real-time neural pulse-pattern feature extraction and recognition

J. -D. Tai; W. M. Gosney; L. L. Howard; G. W. Gross [1992] Proceedings of the 35th Midwest Symposium on Circuits and Systems, 1992

Presents the algorithm and implementation of real-time feature extraction and pattern recognition for signals from a cultured living neural-cell network. Feature extraction and pattern recognition are achieved by the application of data compression techniques and an artificial neural network (ANN). The implementation consists of a 80386-based PC and a TMS320C30 digital signal processing (DSP) card that is inserted into an ...


Time-frequency analysis of high-frequency activity at the start of epileptic seizures

M. Sun; M. L. Scheuer; S. Qian; S. B. Baumann; P. D. Adelson; R. J. Sclabassi Engineering in Medicine and Biology Society, 1997. Proceedings of the 19th Annual International Conference of the IEEE, 1997

High-frequency activity in the subdural electroencephalogram (SEEGs) often appears preceding full-scale epileptic seizures. This activity may provide important information about the location of epileptic foci and the propagation of seizures within the brain. To characterize this activity we applied advanced time-frequency analysis techniques, such as the cone-kernel distribution and time-frequency signal reconstruction, to multichannel SEEG data. The data shows that ...


Recent applications of particle image velocimetry in large-scale industrial wind tunnels

C. Willert; M. Raffel; J. Kompenhans Instrumentation in Aerospace Simulation Facilities, 1997. ICIASF '97 Record., International Congress on, 1997

A variety of particle image velocimetry (PIV) systems for use in industrial wind tunnels have been developed at DLR in the past decade. Given the high operational costs of modern wind tunnels and the required instrumentation, the PIV system design emphasis concentrates on portability, modularity and reliability. Typical applications require large observation distances (>5 m) and relatively large observation areas ...


Spectrum shaping constrained codes for recording

B. Vasic; S. Denic; R. Rathnakumar Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2005

The paper gives a survey of spectrum shaping codes used for digital recording systems. This class of codes belongs to the broader class of modulation codes, which are widely used in recording systems for adjusting the source characteristics to the characteristics of the recording channel. The Shannon noiseless capacities of recording channels are considered, as well as the spectra of ...
