(a) Map the following standard SOP expression on a Karnaugh map: ABC+ABC+ABC+ABC (b) Determine the minimum SOP expression from the map. (c) Draw a Karnaugh map and find the simplified expression for the following minterm function: F(A,B,C,D)=m(0,1,2,3,4,5,6,7,12,14,15) (d) Use a Karnaugh map to reduce the following expression to a minimum SOP form: AB+AB+CD+CD
