Bangladesh University of Engineering and Technology

Department of Computer Science and Engineering

Course: CSE 206


Digital Logic Design Sessional

Experiment No. 4
Arithmetic circuit design.

1. Design a 1-bit full Subtractor circuit using logic gates.

2. Using basic gates, design a 2-bit comparator to compare two 2-bit numbers X and
Y . The circuit should provide 3 output lines to indicate X > Y , X = Y , and
X <Y.

Lab Sheet: For each of the problems/questions, your report should cover the following
points:

• Problem specification.

• Required IC chips.

• Truth table.

• Simplification steps.

• Required equation in minimized form.

• Circuit diagram with pin number.

Answer the following question.

1. Design a 4-bit Carry Look Ahead (CLA) adder circuit.

2. Add an overflow output to your adder circuit. The overflow output should be on
whenever the output is too large to be represented by 4 bits.

3. Design a 4-bit BCD (8-4-2-1) adder.
