A circuit that adds two 3-bit numbers using a half-adder and a full-adder.

A circuit that takes two decimal numbers A and B as input and then splits in into their corresponding three bits using a splitter and then calculates their summation using XOR, AND and OR gates. This generates 4 output lines for 4 bits of the summation, and a reversed splitter is finally used to join the output lines to produce a 4-bit output and displayed using a Hex-Display.

This is a ripple-carry adder.

The circuit was made by a beginner to get some experience working with logic gates, k-maps and simulation software, there are many things that can be improved. Open for suggestions.

A collection of binary adders with Binary, Hex, and Decimal input and output representation

3-bit sequential adder that saves the output sum to a 4-bit shift register and displays the output on a hex 7-segment display.
