i need to design a voltage triggered switch circuit...
basically the input is varying from 0 to 20v..
i need the output high when the input is between 0 to 2v
and the output should be low as it crosses 2v upto 20v
actually i am a mechanical student...this is a project on automobile electronics...my electronics is off!!please be kind enough to explain me in detail...or if you can help me with any of your ready circuit it would be beneficial....
