功率放大器的额定功率指标应该怎样确定?这是一个长期有争议的问题,国外也是一样,虽然二、三十年来人们作了很多研究工作,但是直到1975年底尚有文章进行这方面的讨论~[1]。过去,由于对此问题重视不足,往往在实际上降低了电声设备的放声质量,亦即增加
How to determine the rated power index of the power amplifier? This is a long-standing controversial issue. The same is true in foreign countries. Although much research has been done in two or three decades, there are still articles in this area discussed by the end of 1975 ~ 1]. In the past, due to lack of attention to this issue, the sound quality of the electroacoustic equipment is often reduced, that is, increased
