Statement of Purpose [理工科讀書計畫代寫範例 ]

Electrical and Control Engineering Departmentat AAAAA University led me into the realm of electric machinery and helped mehold firm my planning for further studies in this discipline.  I wasmajored in Mechanical Engineering at the time when I was admitted to AAUniversity and later I decided to commit myself to the stud of Dynamo-electricsthanks to my interest in Electrics when taking up the course of General PhysicsII (Freshman year in Spring 2001).  Transferred to Department ofElectrical and Control Engineering upon completing my freshman year with anexcellent achievement of Top 2 and the hard studies in then coming three yearsproved my choice is correct.  Among all the related disciplines, I amparticularly fascinated in the area of Intelligent Machine and my achievementin the study of Intelligent Machine is very outstanding.  I’ve chosenControl System and DSP as the objectives for my further exploration since theyare the very basics of Intelligent Machine.

Upon completing the basic requirements, Iselected Intelligent Machine and Signal Processing as my core study subjects.  Myselected subjects for Intelligent Machine include DSP Programming, Sensor andInterface, and Introduction to Intelligent machines; and Signal Processing,Introduction to DSP, and Principles of communication system.  In theassociated courses, I took Linear control system I, II and Labs, andIntroduction to Image processing and recognition.  All these courseshave trained me on how to apply theories into practical operation in lab worksand project studies.My GPA reported 3.42; and that for the final 60 credits,3.65 showing I was making progress and became better competent in facingchallenging upper level courses.  Hence, I am very confident andready in taking further studies in graduate school.Lab works of Electronics LabIII, Control Labs and DSP programming Labs impressed me and paid the bestbenefits for me.  Electrics lab III is the Prerequisite of ControlLabs.  In Control Labs, we present block diagram in linear controlsystem in the form of circuitry followed with the completion of experiments.  Forexample, P.I.D controller and Lead/Lag compensator were respectively expressedin circuit block, and in Electrics Lab III we designed each Functional CircuitBlock to find out the circuit operation followed with zero-in test to ensure noerror to be carried over to Control Labs.  In Control Lab we used allcircuit blocks to simulate Block Diagram in Linear Control System.  Allthe important theories about Linear Control System were verified in ControlLabs.  We were instructed to take advantage of Matlab’s Simulinkfunctions to complete Pre-lab simulation.  All these trainingsinvolving mutual comparisons between simulation and hands-on helped me befamiliar with and develop better programming proficiency in Matlab.

In thecourse of DSP programming and Labs, we applied TMS320VC5402 DSP Starter Kitfurnished by Texas Instrument to writ programs in Assembly Language to run DSPoperation rules –Real Time Fast Fourier Transform etc., and concluded aproject.  In the project, we searched for those characteristicfrequencies of musical sound to simulate sounds played by various types ofmusical instruments through string waves synthesis, and further to edit into afragment of music accompanied with chorus.  This project helped mebetter understanding presentation and analysis of audio signals in theFrequency Domain.

During my junior year, (Fall 2002~Spring2003) I participated in the workshop of MP3 and Bluetooth wireless transmissionoffered by Professors LIN, Tjin-deng, LIN, Tjein-yo, PHD, and LIO, Te-cheng,PHD.  The workshop highlighted the production using Bluetoothtransmission of a Wireless Recordable MP3 player.  Based on Bluetoothtransmission, we wrote Assembly language using Microprocessor 8051 to controlMp3 en/decoder chip in achieving the function of wireless audiorecording.  We successfully commanded 8051 to control Micronas 3587FMpeg layer 3 de/encoder to permit storage of audio data into the memory of achip.  Through the Project, I was familiar with Bluetooth protocoland MP3 file specification, and knowing how to using chip’s Data sheet to testthe chip, and applying what I had learnt from Assembly language programming inMicrocomputer system in the Project. The rewarding experience in the series oflab works and workshop lent me more interest in control system and DSP;furthermore, I developed better appreciation of teamwork spirits, skills ofcoordination and communication, pragmatic research, independent operation, andexpression capabilities in writing and speech.  Now I am capable ofhandling all related classroom and lab works in the area of electric machinerythanks to my full understanding of the mutual transfer between system’s timeand frequency response and what they stand for the significance in physics.

I plan to spend two years at Electrical andComputer Engineering Department, College Park , University of BBB to take themaster program.  Control in the scope of Information Science andSystems will be my major; and Communication and Signal Processing, my secondmajor with the ambition to extend my studies to Intelligent machine.  Ifind that the Department of UMD offers a complete program for me to furtherexplore into the disciplines of Control system and DSP.   Inaddition, Intelligent Servo-system Laboratory at the Department is proud ofmaintaining extensive scope of research and achievements that fit mycommitments of future studies so well.  

Intelligent System is playing an even moreimportant role in our lives.  Reports have indicated that Robots willexit automobiles in future.   Whereas improving life conveniencefor the mankind is the mission of an engineer, I am willing and ready to firmlycommit to the study of Intelligent System. Profession W, Ku-yang, the Dean of Department once told methat a person with a master degree is the one who is able to independentlycomplete studies and solve problems challenged while a person with a PhD is theone who is able to identify in-depth issues justifying investment of researchefforts in a particular area and to explore into it until the question isanswered.  Upon completingmy master program, I wish to continue taking PhD program so to prepare myselfin the territory of electric machinery the agile thinking and capabilitysufficient for me to do my contribution in making our lives easier and moreconvenient.
