4-Bit Full Adder using Logic Gates. This is an outstanding project for the Digital Logic Design Students that is based upon the Logic Circuits.It is a simple, creative and interesting project in which ...

Learn how to use logic gates and circuit diagrams to create a simple calculator that can perform addition and subtraction with four-bit numbers. Sign in to view more content ...

4bit adder and Subtractor As we learned from DLD course, we can build 4bit adder by cascading four 1bit full-adders. So in this Assignment I preferred to build every component from the basic logic ...

In the Modern computers for performing the operation of ALU (Arithmetic Logic Unit) like Addition, Subtraction, different types of adders are using for achieving low delay and fast output. QSD numbers ...

Everything is modular, so four of his 4-bit adder cards eventually get together to form a 16-bit adder, which we assume will be used to build out a very noisy yet entertaining ALU.

This full adder is constructed using two Feynman gates and a multiplexer. Fig. 8: Internal RTL of a reversible full adder. A Feynman Gate is a 2*2 reversible logic circuit. This gate placed in the ...
