3. ACKNOWLEDGEMENT
First of all I would like to thank almighty GOD who has given this wonderful gift of life
to us. He is the one who is guiding us in right direction to follow noble path of humanity.
In my Four weeks industrial training it is a wonderful experience to be a part of it where
I have opportunity to work under brilliant minds. I owe my deep regards for the
supporting and kind staff authorities who are helping me in my lean patches during these
Four weeks. The knowledge I am gaining throughout my studies have the practical
implementation during this period. I am grateful to all the staff of the company and for
their timely support and sharing of their experience with me. I would like to express my
heartiest concern for able guidance and for inspiring attitude, praiseworthy attitude and
honest support.Last but not the least I would express my utmost regards for the
Electronics and Communication Department of our Institute.
