ACKNOWLEDGMENT
First and the most important person that help me for the whole this two semester PM. DR. Zahriladha bin Zakaria. Thank you for your guidance help me to understand about this project. His guidance from the beginning to make me understand about the project until the completion of this thesis. Thank you for spending your valuable time to keep me on track while completing my project.
I also would like to give the appreciation to the Dean’s of faculty of Electronic and Computer Engineering and also the lecturers who contribute during the seminar thesis writing. Dr. Kok Swee Leong, the coordinator of PSM programme for his inestimable and invaluable guidance. Thanks so much for taking time from your busy schedule togive an introduction about this PSM program and provided the sources of the courses.
I am thankful to technician PSM Lab, Encik Imran Bin Mohamed Ali and technician Makmal Penyelidikan I, Encik Mohd Sufian Bin Abu Talib for helping me during the fabrication and measurement process.
