To convert the circuit for F(A,B,C,D) = AB'C' + BC'D + AB'D to a 3 level NAND circuit would require:
factor AB' from AB'C' + AB'D
factor B' from AB'C' + AB'D
factor D from BC'D + AB'D
factor C' from AB'C' + BC'D
none of these
Answer Factor from .
minimum 2 variables factor is required here for 3 level nand gates so only option 1 is correct .
Rest of the options have 4 level nand gates beacuse factoring is of only one variable.
Thank You.
