This project is a hardware-only 4-bit binary adder-subtractor circuit built using DIP switches, TTL logic ICs, and seven-segment displays. It performs addition and subtraction of two 4-bit binary ...

Micro-electronic devices are playing a very prominent role in electronic equipment’s which are used in daily life. For electronic equipment battery life is important. So, in order to reduce the power ...

This repository contains the design and simulation of a BCD (Binary-Coded Decimal) adder circuit using Logisim. BCD is a class of binary encodings of decimal numbers where each decimal digit is ...

When anyone is first introduced to the topic of digital computers, they are almost invariably told that these machines are based on binary (base-2) logic and the binary number system, where “binary” ...

Abstract: Reversible logic is one of the emerging technologies having promising applications in quantum computing. In this work, we present new design of the reversible BCD adder that has been ...

Abstract: An all-optical binary-coded decimal (BCD) adder with the help of Terahertz Optical Asymmetric Demultiplexer (TOAD) is proposed and described. The paper describes the all optical BCD adder by ...

How do you create a full adder using nand gates? A Full-adder circuit adds three one-bit binary numbers (A, B, Cin) and outputs two one-bit binary numbers, a Sum (S) and a carry (Cout). It is usually ...
