I need to use combinational logic to produce a high ouput for a certain range of values. I have and anaolgue signal which i have converted to a 12 bit digital signal, I need an LED to be turned on when the analogue signal is above a certain voltage.(adsbygoogle = window.adsbygoogle || []).push({});

I have the digital value (101001110100 = 6V), now I need the LED to be turned on for all values between this and 111111111111. SO i guess what I am asking is there any shortcut for implenenting logic for all values above a specified one. I hate to think that im going to have to go through and write an SOP for all the intermeiate values, and then it is impossible to put on a karnaugh map to simplify (humanly impossible).

So does anyone know of a shortcut for implementing this seemingly simple logic function?

Many Thanks
