For

B0 = (!A1 . !A2 . !A3) + (A2 . A1 . !A3) + (A3 .A2 . !A1) + (A3 . A1 . !A2)

B1= ( !A0 .A1) + ( A0 . !A2 . !A3 ) + ( A0 .A2 .A3 )

B2= (A0 .A2) + (A2 . !A1) + (A1 . !A0 . !A3)

B3=(A3 . A0 ) + (A3 . A1) + (A2 . A0 . !A1)

Where B0,B1,B2,B3 are outputs and A0,A1,A2,A3 are inputs

dot (.) = AND

+ = OR

! = NOT

Please draw a circuit diagram for this using AS FEW GATE AS POSSIBLE.

Thank you and please try to do it using as few gate as possible.
