A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

Biochemical circuits made of rationally designed DNA molecules are proofs of concept for embedding control within complex molecular environments. They hold promise for transforming the current ...

It’s my own fault. I have only myself to blame. I knew I was opening a can of worms when I first thought about writing a column on the topic of applying pull-up and pull-down resistors to the inputs ...

In the first installment of this course, we learned that a digital value is a quantity that varies “in steps” and can take on only a finite number of values. In today’s logic systems, only two ...

All systems can be understood using an input-process-output (IPO) model, and the system we call “innovation” is no exception. This model is likely familiar to you from information technology and ...

Implementing I-P-O into your current projects can be a fast and visual way of understanding workflow. While it can seem ...

Logic gates are the fundamental building blocks of computers, and researchers at the University of Rochester have now developed the fastest ones ever created. By zapping graphene and gold with laser ...

I fear the topic of this column is poised to unleash a tsunami of controversy. My engineering accomplice Joe Farr says that this is one of those topics that, when presented to 10 different engineers, ...
