a) Finish the following truth table of a 2-to-4 binary decoder with active-high output, whose logic symbol is shown below. Assume that 'x1' is the most significant bit in the input and 'x0' is the least significant bit in the input. x1 z0 2-to-4 z1 x0 decoder z2 z3 x1 x0 zo zl z2 z3 b) Use the 2-to-4 decoder above to implement the logic function F(x1,x0) = (x1+ x0)(x1+x0). You may use an additional logic gate.
