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...

1- A) The SR latch is different from combinational circuits because it preserves state. That is, unlike combinational circuits, if the inputs change, the circuit keeps its present state. Say that the present state of the SR latch is “set”. We change the values on the two input pins, and the state does not change. What is the value on those input pins? 1- B) Assume that you have a D flip-flop module available to you. Treat it like a...
