(a) Find the simplest boolean function in the product of sum (POS) form of the following function: f(w,x,y,z) = N(0,1,2,3,7,8,11,13) and d(w,x,y,z) = E(5,9,14,15) (b) Given two boolean functions f and g. then, the functionh = fg is obtained by ANDing the two functions, the result of If which is a common minterm that exists in both f and g. f= wxy' + y'z + w'yz' + x'yz' and g = (w+x+y'+z') (x'+y'+z) (w'+y+z') then using the karnaugh map, find the simplest form of h = fg
