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. (

An optimization of modulation codes in digital recording

Horiguchi, T.; Morita, K. Magnetics, IEEE Transactions on, 1976

A few new modulation codes(or run-length-limited codes) in digital magnetic recording is presented. Linear density limits of the new codes and the existing codes are evaluated for a typical recording channel. One of the new codes shows the highest linear density limit among the existing codes and is improved over, for example, MFM and 4/5-rate-NRZI codes by about 20% to ...

An HDTV compression scheme for production-quality recording and high-performance shuttle operation

McLaren, D.L.; Gersho, A. Consumer Electronics, IEEE Transactions on, 1993

A novel scheme is proposed for the efficient coding and compression of high- definition television (HDTV) sequences for recording on digital video tape. The scheme achieves a constant 8:1 compression ratio by exploiting both intraframe and interframe compression techniques and removing both statistical and psychovisual redundancies during the coding process. However, a perceptually lossless image quality is still maintained after ...

IEEE Guide for Transformer Impulse Tests - Redline

IEEE Std C57.98-2011 (Revision of IEEE Std C57.98-1993) - Redline, 2012

Transformer connections, test methods, circuit configurations, failure analysis of lightning impulse, and switching impulse testing of power transformers are addressed. This guide is also generally applicable to distribution and instrument transformers.

Remote Failure Analysis of Micro-Based Instrumentation

Zick, G.L.; Sheffer, T.T. Computer, 1977

Microprocessors have brought flexibility and versatility to a wide range of instrumentation. They have brought new problems as well. Two such problems-the difficulty of remote reprogramming and the need in certain circumstances for peripheral storage-can be especially troublesome for the design engineer who needs to test his prototype instruments at the site of application.
