— PHYS 375: Lab 12 – Multiplexers –PurposesBuild and use circuit based on multiplexers and decoders.1 Digital multiplexerBuild the circuit shown in Figure 1. Use a 1 kΩ SIP resistor network and an 8-bits DIP switch for thedata input.1. Set the input data D7-D0 to 10101100 and make a truth table for the output Q.2. A variant of this circuit was discussed in the cla ss, briefly remind what it is supposed to do andwhy the D7-D0 switch were chosen per the values aforementioned.3. Does this system behave as a prime number generator?Figure 1: Circuit for part 1.2 Seven segment displayBuild the circuit shown in Figure 2 . Note that each switch should be connected to one input of thedisplay.1. Which switch turns on w hich light?2. Make a table with all possible cases .1Figure 2: Circuit for part 2.3 Four-bits decoderAdd a decoder on the previous circuit to modify the circuit accordingly to what shown in Figure 3.1. Make a truth table for all possible input for the decoder, its outputs and the displayed pattern2. Conclusion – what do you display?Figure 3: Circuit for part 3.2multiplexer decoder displayFigure 4: Nomenclature for the three devices used in this
