Problem 1 (20 pts): Consider the following Boolean function F(A,B,C,D)=sum m(0,1,2,8,9,10,11,12,13,14,15) Use a K-map to find a minimum SOP expression for F. Circle your final answer. Problem 2 (20 pts): Consider the following Boolean function Use a K-map to find a minimum SOP expression for F. Circle your final answer. Problem 3 (20 pts): Consider the following diagram: What's the standard SOP expression of output F? Express your answer in shorthand notation and circle your final answer. Problem 4 (40 pts): Design a 2-bit comparator. The circuit takes two 2-bit numbers A and B as input and outputs 1 if and only if A>=B. Draw a block diagram (5 pts), generate a truth table for the circuit (10 pts), get a minimum SOP expression for the output (10 pts), and draw a logic diagram of the circuit (5 pts). Simulate your circuit using Logisim and submit a screenshot of your Logisim circuit diagram (10 pts).

4. (10pts) The differential equation $(2x - y) + (2y - x)y' = 0$ is exact. Solve the initial value problem $(2x - y) + (2y - x)y' = 0$ and $y(1) = 3$ 5. Consider the (autonomous) differential equation $y' = f(y) = y^2(1 - y)$. Do not solve the differential equation! (a) (5pts)Plot the graph of $f(y)$ and the phase line. (b) (5pts) Determine the equilibrium solutions and classify each of them by unstable, asymptotically stable, semistable. (c) (5pts) Describe the long term behavior (that is, the behavior as $t \to \infty$) of the solutions to the IVP for various values of $y(0) = y_0$. Give as complete a description as possible.
