Abstract
A circuit for indicating of three-state is developed.It is made up of NOT gate、two-colour light emiting diode and so on.It cleverly uses of the specific property of transfer from gate c ircuits and that of volt and ampere light emiting diode(LED).And it realizes the identifying and instruction for the logical state of three state.It can also a ccomplish the watch and measure for high or low volt power supply.This paper exp ounds the working principle and main points for designing of circuits.关键词
