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 ...

Abstract: In this paper, the low power and reduce Ground Bounce noise 4 bit adder has been proposed. Full adder is the most important basic building block of digital circuits employing arithmetic ...

This was a mini project done over the course of a weekend after having had my interest in computer hardware spiked due to a course in computer system architecture that I was taking. Let's do a quick ...

Would you consider this to be doing math the old-fashioned way? Instead of going with silicon-based switching (ie: transistors) this 4-bit adder uses mechanical relays. We like it for its mess of ...
