EE 320 – Homework #2 1. Construct a truth table for each of the following Boolean functions: a) AB+(BC)’ b) (AB)’(A+C)’ c) AB’+BC’ 2. Prove the following relations: a) (A+B)’(A’+B’)’=0 b) X+XY+XZ=X c) X+X’Y+(XY)’=1 3. Express the following functions in their canonical S.O.P and P.O.S form: a) F(A,B,C,D)=D(A’+B)+B’D b) F(A,B,C)=(A’+B)(B’+C) c) F(X,Y,Z)=(XY+Z)(Y+XZ)

Design a combinational circuit using the minimum number of NOR gates and inputs to realize the following functions. The circuit has four inputs A,B,C and D representing a decimal digit in BCD (A is the MSB) and a single output which is equal to 1 whenever the value of digit is less than 3 or more than 7. (Use K-MAP) 6. Design a combinational circuit that accepts a three-bit number and generates an output binary equal to the square of the input number....
