Use a 4bit decoder and a layer of NOR gates to convert 4bit

Use a 4-bit decoder and a layer of NOR gates to convert 4-bit binary numbers into their equivalent hexadecimal values displayed on the 7 segment display. Display 10 - 15_10 as A, b, C, d, E, F (in other words, small b and d). Save the resulting circuit as a new logic symbol to be used in problem 3. Don\'t forget that the seven-segment displays on the Basys board are active-low.

Solution

let 4 bit decoder is xyzw

its hexadecimal part

= 8x + 4y + 2z+w

it is now passed through NOR Gate

we got

12 and 14 value

C & F
