Using digital logic gates such as AND, OR, XOR, NOT, NAND, NOR, and XNOR and other related logic functions is often the foundation for defining the relationship between electrical signals and how they ...

You will all no doubt be familiar with the 74 series logic integrated circuits, they provide the glue logic for countless projects. If you look back through old listings of the series you’ll find ...

A (long) while ago I presented you the Easy-phi project, which aims at building a simple, cheap but intelligent rack-based open hardware/software platform for hobbyists. With this project, you simply ...

Now, the thing to remember is that we are using a CD4512 chip, whose truth table is shown below. The important thing to note here is that, in addition to the three multiplexer select controls, A, B, ...

Researchers at Manchester University in the UK have used graphene to make a new electrically-controlled switching device that supports both memory and logic functions. The device, which exploits ...
