EE 320 – Homework #4 1. Using 8 data input selector logic (MUX), implement the following two functions: a) F(A,B,C)=S 0 S 2 S 3 S 5 b) F(A,B,C,D)=P 0 +P 1 +P 5 +P 7 +P 8 +P 10 +P 14 +P 15 2. Using 3/8 binary decoder, implement the following function following function: F(A,B,C)=P 0 +P 2 +P 3 +P 5 3. Using 4x1 MUX’s implement the following functions: a) F(A,B,C)=P 0 +P 5 +P 6 +P 7 b) F(A,B,C)=S 1 S 3 S 4 S 6 c) F(A,B,C,D)=P 0 +P 3 +P 5 +P +P 13 +P 15 4. Design an encoder that will encode ten decimal digits into their excess-3 code.

EE 320 – Homework #4 5. Design the full adder/subtractor shown in Figure below. There are four inputs (A i , B i , CB i and F) and two outputs (SD and CB 0 ). The input F is a control signal such that when F=0 the circuit works as a full adder:

Unformatted text preview: A i and B i represent the two bits to be added. Cb i represents the input carry. SD represents the output sum SD represents the output sum. CB represents the output carry and when F=1 the circuit works as a full subtractor and: A i and B i represent the two binary bits to be subtracted. CB i represents the input borrow. SD represents the output difference. CB represents the output borrow. Implement the circuit using the minimum number of gates.
