1.  Seven Segment Display Driver:

  (a)  Write the Truth Tables for any 2 segments of a 7 segment
         display when used to display all the Hex numbers.
  (b)  Transfer the Truth tables to Karnaugh maps and derive a
         minimal Sum of Products expression for each segment.
  (c)  Draw circuit diagrams for the SOP expressions USING ONLY
        NAND GATES.
  (d)  From the original truth tables shown in part (a) derive
         implementations for the two segments using an 8 input
         multiplexer for each segment.
  (e)  Implement both the SOP expressions in (c) and the multiplexer
        circuits in (d) using Logic Works, B²Logic, Circuit Maker,
        or LogiMac.
  (f)  Test your circuits by using all 16 possible inputs ( 0 - F ) and
        turn in both the circuits and timing diagrams.  You will find it
        easiest if you use the Hex Keypad or the 4 bit input if the keypad
        is not included in the parts that are available..
  (g)  Using the original Truth Tables for the 2 segments that you
         have chosen, write the POS equations.
