Discrete-time Models for Digital Magnetic Recording

نویسنده

  • J. BERGMANS
چکیده

Using a fundamental result from detection theory, this paper translates the most popular continuous-time models for digital magnetic recording into simple discrete-time models which are equivalent from an information transfer point of view, and which are closely related to the optimum performances of all commonly applied receiver types. The models take account of the head-to-medium spacing, medium thickness, playback head gap size, tape speed, transmission code and information density, and are valid for both longitudinally and perpendicularly magnetized media.

Improvement of position measurement for 6R robot using magnetic encoder AS5045

Recording the variation of joint angles as a feedback to the control unit is frequent in articulated arms. In this paper, magnetic sensor AS5045, which is a contactless encoder, is employed to measure joint angles of 6R robot and the performance of that is examined. The sensor has a low volume, two digital outputs and provides a high resolution measurement for users; furthermore its zero positi...

Effects of non-newtonian properties of blood flow on magnetic nanoparticle targeted drug delivery

Objective(s): One applications of nanotechnology is in the area of medicine which is called nanomedicine. Primary instruments in nanomedicine can help us to detect diseases and used for drug delivery to inaccessible areas of human tissues. An important issue in simulating the motion of nanoparticles is modeling blood flow as a Newtonian or non-Newtonian fluid. Sometimes blood flow is simulated ...

Direct Conversions Between DV Format DCT and Ordinary DCT

digital recording, DVC format, 8-8 DCT, 2-4-8 DCT A fast algorithm is developed for direct conversions between the 2-4-8 DCT mode associated with the digital video cassette (DVC) standard and the ordinary 8-8 DCT associated with other formats of compressed video. The algorithm avoids explicit transformations to and from the original pixel domain and thus saves a considerable amount of computati...

A new method for acquisition and analysis of single unit recording data

Single unit recording has been used as a well-known technique to study the electrical behavior of neurons. In this respect, the classical methods are rather expensive. In this study a simple and inexpensive method for single unit recording studies has been introduced. Computer sound card was used for data acquisition. Neural responses were saved via simple sound applicable packages and then ana...

Modeling and Evaluation of Stochastic Discrete-Event Systems with RayLang Formalism

In recent years, formal methods have been used as an important tool for performance evaluation and verification of a wide range of systems. In the view points of engineers and practitioners, however, there are still some major difficulties in using formal methods. In this paper, we introduce a new formal modeling language to fill the gaps between object-oriented programming languages (OOPLs) us...
