In this paper the need for employing a data reduction algorithm in using digital graphic systems to display biomedical signals is firstly addressed and then, some such algorithms are compared from different points of view (such as complexity, real time feasibility, etc.). Subsequently, it is concluded that Turning Point algorithm can be a suitable one for real time implementation on a microproc...

A microcomputer-based simulator for digital control systems is proposed. The proposed simulator is a hybrid system in which the plant is simulated by conventional method of analog computers and other parts of the system including generation of input signal is performed digitally, using a Z-80 based microcomputer. To overcome the difficulty of programming in assembly language, and at the same ti...

Digital Libraries have gained tremendous interest with several research projects addressing the wealth of challenges in this eld. While computational intelligence systems are being used for speciic tasks in this arena, the majority of projects relies on conventional techniques for the basic structure of the library itself. With the SOMLib project we created a digital library system that uses a ...

Digital control experiments are important parts of electrical engineering course in modern electrical schools. A virtual digital control experimental system is developed for undergraduates to learn digital control principals and to practice online. Based on the digital control hardware experiment platform, the practical circuit model is developed. And some digital control algorithms are employe...

In digital system design, synchronization ensures that operations occur in the logically correct order, and is a critical hctur in ensuring the correct and reliable system operation. As the physical size of a system increases, or as the speed of operation increases, synchronization plays an increasingly dominant role in the system design. Digital communication has developed a number of techniqu...

The experimental study of a secure chaotic synchronized communication system is presented. The synchronization between two digital chaotic oscillators, serving as a transmitter-receiver scheme, is studied. The oscillators exhibit rich chaotic behavior and are unidirectionally coupled, forming a master-slave topology. Both the input information signal and the transmitted chaotic signal are digit...

Low power and high throughput digital systems are required in the number of applications such as Computer Graphics, Virtual Reality, System Control, Image Processing, and Digital Signal Processing etc. The various approaches suggested by researchers for power efficient high throughput architectures include pipelining, parallelism, retiming, folding-unfolding, using multiprocessor environment et...

The baseband digital pre-distortion (DPD) signal processing technique is the most cost-effective linearisation method among other techniques to address nonlinearity effect of power amplifier. For communication systems containing DPD and amplifier, it difficult acquire performance metrics closed-forms for any architecture since there was no mathematical expression each coefficient. Usually, rese...
