Design the circuit for f(A,B,C,D)=ΠM(0,1,4,7,8,12-15),d(2,3,10) using a minimal number of 3-to-8 line decoders and NAND gates (any size). Decoder outputs must be active-low. Also, assume that the decoder has one active-high enable line G0. If you need NOT gates, you must show them in the diagram using NAND gates.

8. For this problem, you are to design a simple combinational logic circuit and then use Logisim to simulate and test the circuit. The circuit is a 2- bit priority encoder with inputs X2 and X1 and outputs Y1 and Yo. The circuit behaves as follows: oIf X2X1 00, then Y1Yo 00 (no active input) If X2X1 01, then Y1Yo = 01 (low-priority input, X1, is active) If X2X1 1-, then Y1Y0 10 (high-priority input, X2, is active) Note that...

You have a 3-to-8 line decoder, an 8-to-3 priority encoder, an 8-channel multiplexer, and an 8-channel demultiplexer. Which would be most appropriate to use in each of the following situations. 1. A 6-position rotary dial provides an active signal on exactly one of its 6 outputs at a time. You want to use fewer wires to represent the switch position. 2. A digital signal from a microphone needs to be routed to one of seven classrooms so that you can...
