ENGRD 230 White Midterm Answers for Fall 2006 Problem 1: a. F = X'*Y*Z' + X'*Y*Z + X*Y'*Z + X*Y*Z b. There is no one correct answer here. The simplest way to create the circuit is to first draw the gates and then draw the corresponding transistor circuit. Some simplification may result by starting with a NAND for the output gate. An inverter and three 2-input NANDs will do it (14 transistors). Minimization was not necessary. c. F=sum(2,3,5,7) c. F=prod(0,1,4,6) Problem 2: a. A resistor in series with a battery. b. R_T = 1200 ohms. c. V_T = 2.0 V. d. A 200 ohm resistor to ground. e. 0.286 V. f. LL, LH, HL. Problem 3:
