Assignment 3 (CLO 3)
ECE-161 Digital Logic Design
Deadline: Friday, May 10, 3:00 pm
Q.1
Design a binary multiplier to multiply two 4-bit numbers by utilizing AND gates and binary adders
in the design.
Q. 2
You are required to design a combinational logic circuit that takes two 4-bit numbers A and B
and a 1-bit input C. The circuit should function as an adder or a subtractor of the inputs A and B,
such that based on the input C it toggles between addition and subtraction. Assume that A>B.
Q.3
Design a combinational circuit based on the given three Boolean functions.
F₁(A,B,C)=(2, 4, 7)
F₂(A,B,C)=(0,3)
F3(A,B,C)=(0, 2, 3, 4, 7)
Implement the circuit using a decoder constructed with NAND gates and "NAND or AND" gates
connected to the decoder outputs.
