TL;DR: The development of a Virtual Remote Electronic Laboratory and its implementation using National Instrument's LabVIEW is discussed and a digital signal processing course taught in the Department of Electronic Engineering at Sir Syed University of Engineering and Technology is selected.
Abstract: In this paper the development of a Virtual Remote Electronic Laboratory and its implementation using National Instrument's LabVIEW is discussed. The techniques presented in this paper are general purpose and can be used to develop any laboratory that requires simulation, hands-on experience, and the ability to run the laboratory over a network of computers. As a case study a digital signal processing course taught in the Department of Electronic Engineering at Sir Syed University of Engineering and Technology is selected. The practical implementation of this laboratory using LabVIEW is also discussed in this paper. The main advantage of this laboratory is that the students can perform the experiments of different subjects remotely through the Internet. Engineering education has always been dynamically interrelated with technology change. Educators and researchers worldwide are using National Instrument's products to automate routine tasks, accomplish new objectives, replace outdated and expensive equipment, and demonstrate students the potential of high technology. Physical systems are modeled and manipulated in software, and realized in hardware to demonstrate what differences may occur with real-life applications. By solving problems using software-based virtual instruments and actual hardware, students gain an appreciation of the interaction of process instrumentation and computers.

TL;DR: An overview on the most adopted technologies for remote control of measurement instrumentation and particular attention is paid on Web services technology that proves to be a general solution, suitable for each type of application
Abstract: For last years, a large number of universities, have been focusing their attention on the opportunity of making students capable to observe experimental activities, from their home and at any time, through Internet. The realization of remote laboratories for engineering disciplines, in particular for a measurement course, presents further problems, since it is required that students interact with remote circuit and handle measurement instruments. The crucial task is, hence, to implement Web/Internet-enabled applications that can be fully controlled and monitored from remote locations. There is a wide variety of solutions enabling the remote control of measurement instrumentation; each one is characterized by its peculiarities, advantages, and drawbacks. In the paper an overview on the most adopted technologies is performed. Particular attention is paid on Web Services technology that proves to be a general solution, suitable for each type of application.

TL;DR: This study concentrates on the problem encounter on the system-computer interface by using a host of interfacing techniques including data acquisition card and parallel and serial interface techniques operating simultaneously.
Abstract: The goal of this paper is to design, develop and demonstrate virtual instrumentation (VI) system that can be used to monitor and remotely control a real-time laboratory experiment. The system has been interfaced with a computer, also used as a server, and the virtual instrumentation has been developed in LabVIEW environment. An important feature of this study is that, the virtual instruments operate on real-time basis collecting, processing, analyzing and displaying data as the events take place. Furthermore, this study concentrates on the problem encounter on the system-computer interface by using a host of interfacing techniques including data acquisition card and parallel and serial interface techniques operating simultaneously. It has been shown that the laboratory experiment can be conducted by the intranet of the enterprise from any location. The problems related with the use of internet due to firewall and others are under investigation

TL;DR: Some peculiar aspects of the instrumentation and measurement courses are discussed, focusing on the impact of e-learning techniques in laboratory activities, and practical hints coming from the authors' experience in in-the-field trials are reported and discussed.
Abstract: E-learning is the one possible evolution of traditional teaching techniques and is becoming a mature technology. Several commercial suites are available to author multimedia courses either to be distributed in physical form (e.g. on CD or DVD) or to be used on-line. However the application of these suites to the instrumentation and measurement courses and in general to courses that require students to learn the use of real devices is difficult and sometime useless. In this paper, some peculiar aspects of the instrumentation and measurement courses are discussed, focusing on the impact of e-learning techniques in laboratory activities. Practical hints coming from the authors' experience in several years of in-the-field trials are reported and discussed.

TL;DR: The techniques of basic instrument showed in this paper can be used to apply to be satiable application in engineering projects and make instruments as simplify clarify and economize.
Abstract: The paper presents the development of a low-cost virtual instrument with LabVIEW. LabVIEW is a powerful development software for signal acquisition, measurement analysis, and data presentation, the flexibility of a programming language with expensive hardware. Because of high-cost, poor engineering students can't learn useful of communication between software and hardware. To help them, the low-cost instrument with LabVIEW occurs. DB25 is a familiar interface because it is the standard for printers and modems. Many instruments have an DB25 interface for connection to computers. Many computers have a DB25 interface port. Both the computer and the instrument need to have the same interface between them. DB25 is generally the least-expensive interface since no additional hardware is needed in the computer. The techniques of basic instrument showed in this paper can be used to apply to be satiable application in engineering projects. Moreover, These specially techniques make instruments as simplify clarify and economize.

TL;DR: A block diagram (BD) based approach that allows one to develop interactive and downloadable signal processing laboratories and it is shown that only a few simple blocks are sufficient for creating many didactic programs.
Abstract: We argue that Java is a natural language to develop interactive teaching material that can be shared and distributed widely. Unlike any other programming language or platform we know, Java development is justified because of its almost universal acceptance. We develop a block diagram (BD) based approach that allows one to develop interactive and downloadable signal processing laboratories. As an example, we show how specific experiments for a DSP class, as well as for an advanced course on wavelets have been developed. The article first explains why the Java language has been chosen, and then describes what has been realized today. Finally, we show how the BD representation can be efficiently used for the development of a wavelet theory course. It is shown that only a few simple blocks are sufficient for creating many didactic programs. This can be seen as an a posteriori justification of the BD model.

TL;DR: A set of Java-based tools for understanding the concepts of convolution, spectral analysis, and pole/zero system response are provided, highly portable and easily accessible to a broader audience of students than comparable systems based on Matlab or other commercial software.
Abstract: One of the key difficulties in a Signals and Systems course is visualization of the mathematically complex concepts presented. Thus, there is a need for graphical tools which enhance the students' comprehension of these difficult concepts by allowing interactive learning. We present a software package to assist in the explanation and visualization of signal processing concepts for an educational environment. We provide a set of Java-based tools for understanding the concepts of convolution, spectral analysis, and pole/zero system response. The wide availability and platform-independence provided by Java make this tool highly portable and easily accessible to a broader audience of students than comparable systems based on Matlab or other commercial software. The software described in this paper is available in the public domain at our website: http://isip.msstate.edu/.

TL;DR: An innovative four year experiment in Internet based distance education involving students and faculty from the University of Colorado at Boulder, George Mason University, Rice University, Cornell University, and Sandia National Labs is reflected on.
Abstract: Distance education is becoming an increasingly important means of reaching a wider variety of traditional and non-traditional students and of developing unique educational partnerships between universities. In an effort to assist engineering departments just beginning to pursue distance education, the authors reflect on an innovative four year experiment in Internet based distance education involving students and faculty from the University of Colorado at Boulder, George Mason University, Rice University, Cornell University, and Sandia National Labs. The educational and research benefits to both the students and faculty are discussed in detail. In addition, the weaknesses and limitations of this experiment are also addressed. It is hoped that these comments and observations will benefit other institutions beginning to pursue similar distance education programs.
