| Abstract: | Unification of analog and digital electric levels is an urgent problem in designing and implementing of digitalization scheme at radio stations. With continuous testing and improvement, the Hunan People's Radio Station has built an electric level system specification which features standard, level clearness and good compatibility. This specification makes the signal channel to achieve the best technical performance in level controlling, and realizes unification of analog level and digital level. Experiences... |
