CEG/EE 260 HW #1 Winter 2010 Due Feb. 17th 2010 (Wednesday), Beginning of Class 1. (20 points ) (1) Draw the logic diagram when an XOR gate is implemented with nothing other than NOR gates. Label the two inputs as A and B and the output as Y. (Hint: Y = XOR(A, B) = (A + B) (A’ + B’). In other words, when you want to implement a Boolean Function using NOR Gates, it is easier if starting from Product-of- Sums. ) 2. (20 points) Obtain the truth table for the following circuit. Draw an equivalent circuit for F with fewer NAND gates. 3. (20 points) For the following function F , where A , B , C , D are all binary variables. IF ( A = 0) THEN { IF ( B = 0) THEN F = D ; ELSE F = 0; } ELSE { IF ( B = 0) THEN F = C ; ELSE F = 1; } (a) Design a circuit that implements the function. You may use any combinational circuit component, including decoders, and multiplexers. (b) Repeat the same question without using anything other than AND, OR, NOT. (Logic gates may have more than two inputs.) The circuit should be as simple as possible. 4.
