Why Electronics?Why learn electronics?Electronic products are commonly used and vital to modern society. Thus, people who understand electronics well have good career prospects. Also, people undertake electronics as a hobby, just as building kites or collecting items or watching movies are hobbies. What is the background needed to learn electronics? An adequate grasp of mathematics (differential calculus, matrix algebra, and signal and system analysis) and physics is a must. How is it best to learn electronics? Although electronics involves mathematics and physics, it is not a pure science. Electronics is suitable to be studied as a craft. A craft is best learned directly under an expert practitioner. But, not all of us have such opportunity and have to rely on books, on-line tutorials, and formal classes to learn electronics. A craft is not a scholarly pursuit, but practice oriented pursuit. Thus, practice, practice, practice or experiment, experiment, experiment is the best way to learn electronics. What exactly do we learn when we learn electronics? Why are you writing this tutorial? All materials or know hows in this tutorial are in the public domain and have been explained in countless test books and web sites beautifully. I am writing this tutorial as a review and a personal resource of electronics. I seek to include more of a context into the materials, and try to filter the materials that I found to be the most useful. Also, I try to present the materials in short dialogue format, which focus the learning. |
