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. (

Diode laser optical recording using trilayer structures

Bartolini, Robert A.; Bell, Alan E.; Spong, Fred W. Quantum Electronics, IEEE Journal of, 1981

A new high-power diode laser and a more sensitive trilayer disk structure useful for FM video and digital data recording have been demonstrated. The diode laser is a constricted double-heterojunction large optical cavity (CDH- LOC) device capable of up to 100 mW output power in a single stable mode. By improving the thermal efficiency of the trilayer structure, the sensitivity ...

Telemetric Seismic Data-Acquisition System

Adam, Vladimir; Urbina, Marianela; Suarez, Ricardo E. Instrumentation and Measurement, IEEE Transactions on, 1985

A system comprising digital telemetry remote stations and an on-line event detection and data recording station has been developed. The remote stations employ time-division multiplexing of up to three seismic sensors operating at sampling rates of 60 samples/s. Higher sampling rates are available if fewer sensors are used per station. The highest single-sensor sampling rate is 240 samples/s. Companding ??-255 ...

IVHM Solutions Using Commercially-available Aircraft Condition Monitoring Systems

Sudolsky, M.D. Aerospace Conference, 2007 IEEE, 2007

Commercial-off-the-shelf (COTS) aircraft condition monitoring system (ACMS) hardware supports critical health management functionality; real-time event forwarding or recording of any parametric/discrete data can be performed using the digital flight data acquisition unit (DFDAU). The ubiquitous DFDAU is the predominant fielded hardware supporting this important functionality -every 737, 757 and 767 airplane must have the unit installed and the same DFDAU ...

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

Mingui Sun; Scheuer, M.L.; Qian, S.; Baumann, Stephen B.; Adelson, P.D.; Sclabassi, R.J. 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 ...
