多谢指正,我是学foreign affairs的,对电路知识仅略知一二。
Dear Mr/Ms Madog,
Many fans are pretty interested in your explanations. If you write in Chinese, it will help more junors to understand technical terms such as Bias, idling current, signal current, high capacity design etc. Some unresponsible manufacturers use coin concepts and terms to mislead entrants.
Anyway, thank you for your contribution.
