| Abstract: | A new design method of wire interactive conversation system is introduced, which uses EM78P447SB chip micro controller signal receiving as main controller, and uses signal generating IC HT9200B and signal receiving IC MT8870, to realize functions of keyboard input, individual call, partial call, all call, incoming telegram display and so on. The system has been utilized practically. |
