Create a 1-bit XOR circuit using only AND, OR, and NOT gates. Explicitly show all steps starting from the truth table for XOR, then listing the logical expressions for when XOR is 1, and then translating the expressions into a circuit.

Give the steps to eliminate useless symbols?

3. Draw the combinational circuit that directly implements the Boolean expression on logisim/circuit lab. If drawn, no extra credit. No excuses. 15 points + 10 points extra credit if drawn and labeled with circuit drawing tools. a. xyz + (y' + z) b. x + xy + y'z c. (x (y z )) + (xz)'

In Matlab 3. Write a program to plot the curve of 5*cos(x) + 10*sin(x). Take x in the domain -pi to pi. Attach the plot screenshot.
