Q4 a. Draw the logic symbol for a 4 line-to-10 line active-low-output BCD decoder. Indicate which lines are input and which are output. Write its truth table only when the inputs values are 1000, 0010 and 0101. b. Draw the logic symbol for a 16-input (16 line) Data Selector/Multiplexer. Indicate which lines are input and which are output. Q4 a. Draw the logic symbol for a 4 line-to-10 line active-low-output BCD decoder. Indicate which lines are input and which are output.
