Connect them one way round and current flows, the other and it doesn ... Thus a signal can be switched on by passing it through a diode in forward bias, and then turned off by putting the ...

As active devices go, it doesn’t get much simpler than a diode. Two terminals. Current flows in one direction and not in the other. Simple, right? Well, then there are examples with useful side ...

This directional control is achieved through precise ... analogs to electronic diodes—allowing computation to be performed ...
