Signaling games are used to model the following situation: Player 1, the Sender, receives some private information and sends a message m E M to Player 2, the Receiver. The latter, in turn, observes m but not 0, and chooses response r E R. Players'payoffs depend on 0, m and r. What could be simpler? Yet, there is a huge number of economically interesting games that fit nicely within this framework: Spence's job market signaling model is the leading example, but applications abound in IO (limit pricing, disclosure...) finance (security design) and political economics

(1)、输入端悬空,Vcc经R1、T1的C结向T2、T3提供基流 T2、T3饱和导通,而T4、D截止,Vo=Vcs3=VL (2)、输入端接>2V电源,设对应的T1e结导通,则V>2.7V ∴-T2、T3饱和导通-Vo=VoL (3)、输入端接同类与非门输出高电平+3.6V——+Vcc经R T1的C结向T2、T3提供基流--T2、T3饱和导通 (4)、输入端接10K电阻到地,若设对应的e结导通,则 输入端相当于接+3V高电平
