2. a) Draw a circuit that generates the following truth table: Selector Inputs Input Output S2 S1 A B X 0 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1 1 1 0 1 0 0 0 0 1 0 1 1 0 1 1 0 1 0 1 1 1 1 1 0 0 0 0 1 0 0 1 1 1 0 1 0 1 1 0 1 1 0 1 1 0 0 1 1 1 0 1 1 1 1 1 0 1 1 1 1 1 0 Hint 1: This circuit uses S2 and S1 to select one of four possible outputs. You will need to draw a selector and decoder plus the four different logic gates
