Indhold

Digital technology has become so widespread that it encompasses nearly all aspects of our everyday lives and we can see its use in handheld gadgets, computers, robotics etc. This free book provides readers with a fundamental understanding of digital system concepts such as logic gates for combinatorial logic circuit design and higher level logic elements such as counters and multiplexers. Undergraduates taking a course in computer science, engineering or information technology will find it useful. Students enrolled in foundation year or pre-university courses will also benefit from the text.

Ramaswamy Palaniappan or fondly known as Palani among friends, received his first degree and MEngSc degree in electrical engineering and PhD degree in microelectronics/biomedical engineering in 1997, 1999 and 2002, respectively from University of Malaya, Kuala Lumpur, Malaysia. He is currently an academic with the School of Computer Science and Electronic Engineering, University of Essex, United Kingdom. Prior to this, he was the Associate Dean and Senior Lecturer at Multimedia University, Malaysia and Research Fellow in the Biomedical Engineering Research Centre-University of Washington Alliance, Nanyang Technological University, Singapore.

He is an expert reviewer for FWF Austrian Science Fund, Collaborative Health Research Projects Program, Natural Sciences and Engineering Research Council of Canada and Industry Grant Scheme, Malaysia. He founded and chaired the Bioinformatics division in Centre for Bioinformatics and Biometrics in Multimedia University, Malaysia. His current research interests include biological signal processing, brain-computer interfaces, biometrics, artificial neural networks, genetic algorithms, and image processing. To date, he has published over 100 papers in peer-reviewed journals, book chapters, and conference proceedings.

Dr. Palaniappan is a senior member of the Institute of Electrical and Electronics Engineers and IEEE Engineering in Medicine and Biology Society, member in Institution of Engineering and Technology, and Biomedical Engineering Society. He also serves as editorial board member for several international journals. His pioneering studies on using brain signals for brain-computer interfaces and biometrics have received international recognition.
