(20 points) Consider the Boolean function of three variables written as a sum of minterm products: F=ABC+ABC+ABC+ABC a. Reduce this function by using a Karnaugh map b. Use Logisim to create the circuit for the reduced function. What function is this circuit performing? c. By taking F from your answer in part (a), use Logisim to create the circuit using only NAND gates. d. Using the Karnaugh map, write out the Boolean function for F by referring to the zeros within the map
