I’m new to this website i was interested by this topic and i want to post my question which is as follows: Design a combinational logic circuit BCD to 7 segment display that displays the 9’s complement of the BCD code on the input. Example if the BCD is 0000 the 7 segment display should display 9 0001 the 7 segment display should display 8 0010 the 7 segment display should display 7 … ….. ….. 0110 the 7 segment display should display 3 … ….. …..
So i tried implementing 4 inputs to a negator to transform the 4 bits into forexample 1111 to 0000 the negation using the not gate to transform into 2’s complement before adding 1 then i implemented 4 full adders to add 1 to the input then im stuck at displaying at the 7 segment display i dont how to connect wires i need help please
please let me know if i have a mistake implementing the full adder wires im not good with wires. its been 4 hours since iam working on this but i found this beautiful site so i said why not try it. ur response is much appreciated.
