This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers. It’s a rather unorthodox use of the part, depending ...

Adders are one of the widely used digital components in digital integrated circuit design. In this paper, various adder structures can be used to execute addition such as serial and parallel ...

In divide & conquer approach the 16 bit number is divided into individual 8 bits. If we continue to divide we reach the leaf level of the problem. In the leaf level of the D&C Tree is a 1 bit adder, ...

In Part 1 of this two-part binary coded decimal (BCD) extravaganza, we introduced a bunch of bodacious concepts, including the binary (base-2) number system, binary logic, binary computers, and bits, ...

Computers built using discrete logic chips? Seen it. Computers from individual transistors? Impressive, but it’s been done. A computer built out of electromechanical relays? Bring on the ozone! The ...
