ㅂㄱㅎ교수님 분반 2021년 1학기 자료입니다!2주차 예비레포트는 당시 의욕에 불타올라서 100% 영어로 썼었으나 그 외 모두 한글입니다...하하...
이번 2주차 예비보고서에는 교수님의 디테일한 피드백 자료가 있어요!
Adobe PDF reader로 열어보면 형광펜 처리된 부분에서 코멘트를 읽으실 수 있습니다.
실험값을 적을 엑셀을 미리 MATLAB과 연동시켜 놓았으므로 실험하면서 돌려보면 이론값과 실시간으로 비교할 수 있어요!
MATLAB코드를 실행하는 것도 파일을 받은 위치만 별도로 입력해주고 실행하면 원하는 그래프가 나오도록 최대한 편리하게 썼습니다.
이때 사용된 이론값은 transfer function만 입력하고 MATLAB에서 계산했거나,
또는 LTspice에서 만든 회로로 계산한 뒤 내보내기한 텍스트 파일이므로 믿을 만합니다.
교안은 다른 교수님 분반과 주제만 동일하고 내용은 아예 다릅니다... 게다가 교수님이 의욕이 크신 만큼 작년에 쓴 자료를 고쳐 쓰실 확률도 꽤 높아요.
그래서 정확히 어떤 교안에 대해 작성한 보고서인지 궁금하실 수 있는데 여기 직접 올려드릴 수는 없고 문의 남겨주시면 확인 도와드리겠습니다!

IV. Concluding Remarks
본문내용
I. IntroductionI.1. Goals
Understanding of 1st order circuit frequency responses, which refers to RC and RL circuits, e.g. LPF and HPF.
I.2. Purposes of Documentation
We can estimate the frequency responses in advance and keep those in mind to verify if our experiment is going well. If measured values are way too far from the estimation, we can check the whole process and find out what was wrong.
II. Summary of Theories
II.1. The Linearity of a Circuit
Generalized for functions in more than one dimension, linearity means the property of a function is compatible with addition and scaling.
When it comes to a circuit, it is about its additivity and homogeneity. Refer to 참고문헌 [9], simply we can say that the linear circuit is an electric circuit and the parameters of this circuit are resistance, capacitance, inductance, etc are constant.
