There are four steps to learn the circuit:
1. Understand the characteristics and working principles of components. Components are the most basic and smallest part of the circuit. You can refer to the website: www.alldatasheet.com (electronic components datasheet, device characteristics, packaging, principles, etc.) More detailed, suitable for reference learning).
2. First learn to look at the circuits of the predecessors and see what functions the circuits of the predecessors have to achieve; understand the basic circuit laws (Ohm’s law, etc.), series and parallel circuit analysis, etc.; after the theory is clear, simulation software can be used for simulation learning, Deepen the impression, do it yourself, weld components, use multimeters and filters for testing, accumulate actual combat experience, combine theory with practice, and get twice the result with half the effort. (Commonly used simulation software includes ISIS 7 Professional, Multisim)
3. Learn to modify the circuits of the predecessors according to your own needs, divide some complex circuits into different modules, analyze them step by step, and then analyze them as a whole to get the results you want.
4. After accumulating rich experience, you should finally try to design circuit diagrams. It is necessary to maintain a non-irritable mentality, find ways to solve problems, practice more practice, and sum up the lessons of failure, so that accurate circuits can be designed.
If you want to learn circuit design well, you have to persevere and not give up. It doesn’t matter if you don’t have a foundation. The important thing is to learn and to be self-motivated. You must study hard at ordinary times, not just relying on theory, more importantly, relying on practical experience.
