Exercise B.7, B.9: Programmable Logic Array (10 points). (a) (4 points) Construct the truth table for a three-input two-output function such that f(x2, 11, xo) pro- duces (A, B) such that A is true only when the number represented by the bit sequence 122100 is prime, and B is true only when the number represented by the bit sequence 121110 is a multiple of 3. (b) (6 points) Implement the above three-input two-output function with a PLA
