Consider following functions:
f1(A,B,C,D) = Summation m(0,2,3,4,5,6,11,12,13,15)
f2(A,B,C) = pi m(0,1,2,4,5)
f3(A,B,C,D) = [D’+AB’+AC’+AC’D+A’C’D]’
f4(A,B,C,D) =Summation m(5,6,9,10)
How many functions are functionally complete?
a)1 b)2 c)3 d)4
given ans is A but i am getting none of these as no function is functionally complete
