CSE 260 Assignment 3
Question 1:
Design a circuit diagram for the following comparator system that takes three 3-bit binary
numbers [A and B] as inputs and outputs in the following fashion:
Output=1; if A-2<B
Output=0; otherwise
NB: For the comparator part, you should only use different gates to build the circuit. You cannot
use a COMPARATOR IC for building that part. For other parts, you may use corresponding ICs.
Question 2:
Design a 18 person voter system using necessary parallel adder(s) only. Use a minimum
number of components in your circuit.
Question 3:
Design a BCD to excess 5 system using necessary parallel adder(s).
Question 4:
Build a circuit that implements the 1’s complement number system (4 bits) using encoder and
decoder.
Question 5:
Implement the following boolean function using a) 16:1 mux b) 8:1 mux c) 2:1 mux d) 4:16
decoder e) 3:8 decoders f) 2:4 decoders
F(A,B,C,D) =∑(0,1,2,7,8,10,11,13, 15)
Make sure that your circuit is efficient, meaning you should use the lowest number of
components.
