| Abstract: | In view of so many kinds of interphones for buildings in the market,a new design of extension in interphones based on AT89S52 is introduced and the design of each part in the whole circuit as well as its working principle is detailed in this paper.At last a simulation is taken for the audio part and the result also expresses that the distortion of this kind is lower than any other kinds in the market.Also by the whole test,this kind of extension is simply composed and operated and has well capability of real-time and speediness so that it has well practicality. |
