Draw a basic ROM array for four$-$bit BCD$-$to$-$excess$-2$ conversion $($CO$5)$

and

Draw the diode ROM architecture for five output functions given below

a$)F_0=m(0,1,3,5,7,9,11,13,15)$

b$)F_1=m(0,2,4,6,8,10,12,14)$

c$)F_2=m(0,1,3,5,7,11,13)$

d$)F_3=m(1,3,6,9,12,15)$

e$)F_4=m(0,1,4,8,12)($ this question is from digital system and I need solutions in step by step$)$
