STATEMENT OF PURPOSE
Albert Einsteins intriguing words, Problems cannot be solved at
the same level of
awareness that created them. formed the corner stone of my
aspirations to pursue
graduate studies, because a high level of education enhances a
persons rationalityand consequently his level of awareness. .
At the culmination of high school I developed a profound
affinity towards
Mathematics & Physics Because of their logical &
analytical nature and wide spread
practical implications to which my graduation certificates hold
testimony. I got to
know the concepts of a semiconductor during the final year at
school and very the
idea of being able to alter the conductivity of a semiconductor
just by varying the
amount of doping and its futuristic applications attracted me,
what followed was the
natural course of events I decided to take Electronics &
Telecommunications at the
undergraduate level
Ever since Electronics has always been a passion for me. As I
delved into the realm
of electronics, my initial fascination turned into one of
unquenchable obsession. My
under graduate program had lots to offer in areas such as
Control Systems, Digital
Signal Processing, Satellite Communication, VLSI Design &
Circuits, Analog
Communication, Micro Processor & Application. Each field in
my discipline attracted
me in its own way; but the fields that appealed to me most were
courses in
Control Systems which was introduced in the second year of
undergraduate study
and then Mechatronics in the subsequent year. Major part of both
the courses were
imparted by Prof. M.J. Khurjekar ,a higly experienced member of
the faculty and a
pioneer in this field with long term industrial experience , his
curiosity and interest in
the field really motivated me to take up Control Systems at the
graduate level .I got
to learn a lot in the classes and lab sessions conducted by him.
The first session in
the labs was devoted to developing simple programs for a Simatic
PLC. A
combination of AND, OR blocks generating a complete control
circuit for a motor
fascinated me. During the subsequent classes I became familiar
with concepts
Ladder diagrams,Actautors,CNC which only affirmed my decision to
take up Control
Systems at the graduate level .
The field of control system has a widespread presence in heavy
industries from a
design of a simple coffee vending machine to a state of the art
PC controlled
robotic arm and i believe there are still other avenues like
using automated bots to
streamline the production in the workshops, work in hazardous
environments, areas
like an automobile manufacturing unit which require a high
degree of precision and
high production values could explored, which is exactly why i
would like to pursue
my graduate level study in control systems at ______. I want to
hone my skills as a
professional of the industry while at the same time contribute
my bit in the research
in this field

To make myself thorough with the very basics of the field i am
presently undertaking
a certificate course in PLC Programming. The course entails the
fundamentals of
Allen Bradley & Siemens PLC, SCADA, Human Machine Interface
& Distributed
Control Systems
Besides core electronics i also got to learn the concepts of
Optical & Microwave
communications in a course on the same and then even got to
implement some of
them during my summer internship at LAMBDA MICROWAVE SYSTEMS
located
at New Delhi, which primarily deals with the designing and
installation of antennas
for microwave application ,in all it was an exhaustive
experience,being a first in the
corporate world. During the time of my internship the company
had decided to
venture into the areas of developing wireless transreceivers so
I was assigned a
project in the R&D unit of the company where in I worked on
the designing of a
wireless FM transmitter receiver system,it was a challenging
task as it required
detailed knowledge of the concepts of selectivity, sensitivity,
fidelity & gain of the
receiver besides also learnt about the fabrication techniques of
the PCBs for the
communication circuits, the various design aspects.
My final year project work was entitled A DSP based Deaf Alarm
System for peoplewith hearing imparity although it was not related
to Control Systems it required anextensive knowledge of the
concepts of Signal Processing. The aim was to fabricate
anintegrated alarm system which would alert the people with this
imparity to varioussound related events like a fire alarm ,door
bell when they are all by themselves at
home.
The system basically consists of a DSP processor, a microphone
unit which takes inputfrom various audible sound sources like door
bell etc and passes it on to the processor(TMS320c5416) which was
programmed to distinguish between the signals on thebasis of their
FFTs and PSD ,once deciphered the detected signal was transmitted
to amobile body worn receiver via a transmitter module .
The processor was interfaced with the mic to accept the real
time signals . We usedCode Composer Studio to dump the code in the
processor but to guard the alarmsystem against false triggering in
the presence of AWGN was a real challenge ,so wecarefully found out
the peak frequencies of each input and then logically coupled
themwith guard bands. In due course of completion of the project
the difficulties faced by meand group members taught us valuable
lessons perseverance and out of the boxthinking . The project has a
lot of scope for the future with a litle more effort thesealarms
could come in as handy and cheaper alternatives to the hearing
aids.
I have always been actively involved in co curricular and extra
curricular activities.Ihave represented my college cricket team at
various intra & inter universitytournaments. I have been an
active member of the organizing committee for the annual
college technical meet and social gathering.
