Digital Design of Signal Processing Systems: A Practical Approach

Acknowledgments

I started my graduate studies at the Georgia Institute of Technology, Atlanta, USA, in January 1991. My area of specialization was digital signal processing. At the institute most of the core courses in signal processing were taught by teachers who had authored textbooks on the subjects. Dr Ronald W. Schafer taught “digital signal processing” using Discrete Time Signal Processing by Oppenheim, Schafer and Buck. Dr Monson H. Hayes taught “advanced signal processing” using his book, Statistical Digital Signal Processing and Modeling. Dr Vijay K. Madisetti taught from his book, VLSI Digital Signal Processing, and Dr Russell M. Mersereau taught from Multi Dimensional Signal Processing by Dudgeon and Mersereau. During the semester when I took a course with Dr Hayes, he was in the process of finalizing his book and would give different chapters of the draft to students as text material. I would always find my advisor, Dr Madisetti, burning the midnight oil while working on his new book.

The seed of desire to write a book in my area of interest was sowed in my heart in those days. After my graduation I had several opportunities to work on real projects in some of the finest engineering organizations in the USA. I worked for In gersoll Rand, Scientific Atlanta, Picture Tel and Cisco Systems. I returned to Pakistan in January 1997 and started teaching in the Department of Computer Engineering at the College of Electrical and Mechanical Engineering (E&ME), National University ...
