2. Given the following canonical expression f(w,x.y,z).. M(1,3,6,1 1,15) a. (15 pts) Use a Karnaugh map to find a minimized SOP expression for f(w,x,y,z). Show that your solution produces the correct truth table. b. (15 pts) Use a Karnaugh map to find a minimized POS expression for f(w,x,y,z). Show that your solution produces the correct truth table. Draw a separate K-map for parts (a) and (b)- don't use a single map for both parts (it becomes too hard to read). Clearly show your groupings
