Design the 'Phone Switch 1.13 Design a 4-input MUX using gates available on the Logic Lab. a) Show the MUX circuit partitioned into one or more MUXs. Use the trapezoidal symbols. b) Show the schematic diagram showing the gates you would put inside each trapezoid in part a). c) Number each gate on your schematic and write the number, in pencil, on the similar gate you will use in the Logic Lab, using the diagram on page 11. (Read Sect 1.17 for a hint on arrangement.) That way you will: (i) know if you run out of a particular gate (ii) be able to find where things are on your trainer after your wiring is done. Trust me, correlating between your schematic and the wiring will be a serious problem.

1.14 Design an 8 output-line DeMUX circuit for your telephone switch using gates available on the Logic Lab. a) Show the circuit partitioned into one or more DeMUXs b) Show the schematic diagram. c) Number each gate on your schematic, and the similar gate you will use on the Logic Lab. 1.15 Check the total number of gates of each type used by the two circuits above. If you do not have enough gates of any type you must do a redesign. Needs to use gates on this
