I was wondering if someone could help me.


   I need to design a simple circuit that will do the following



     Take 4 analogue DC voltages, compare them and give
 4 digital outputs 3 of them at logic 0 and the forth
at logic 1 (this logic 1 output indicates which one of
the four inputs had the highest value)


   Any offers???


   Please E-mail me if you can give me any pointers.




    MORE INFO:


    What I want to do is have 4 light dependent resistors,
 some kind of automatic gain so that the ambient light
level doesn't effect the decision making and I want the
circuit to decide which resistor has the most amount
of light falling on it.

    Is this simple? if so I'd love some ideas.



  Ta,

    Rob.
