11. Draw the output waveform below for output X eiven the inputs (A. B. C. and D) shown below and the following Boolean expression: X = A+B * (CD) + ( BC) 12. If a multiplexer has one output and 24 inputs, how many (minimum number) select lines does the device need to function? Circle the correct answer One Two Three Four Five • 13. If a 74LS138 (3 to 8 Decoder) has a logic "O" on its Output #5 and logic "i's" on all of its other outputs, what are the input conditions for the following signals? (1 or 0) AO (29) = _ A1 (2-) = A2 (22) = E1=_ E2 = _ 3 = (1 or 0) (1 or 0) (1 or 0) (1 or 0) (1 or 0)
