As mention i am given 4 Inputs D C B A and the decoder for outputs for common cathode a b c d e f g.
I need to obtain from 0-9, A-F
So the truth table which i obtained is
D C B A| a b c d e f g
0 0 0 0 |1 1 1 1 1 1 0
....
....
So i made a k map for each segment and how am i suppose to implement the circuit using only basic gates?
this is what i obtain
a = BA'+ DC'B'+DA'+D'B+CB+D'CA+C'B'A' (' means invert)
b = D'C'+D'B'A'+C'B'+D'BA+C'BA'+DB'A
c = ....
d= ....
