Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

What are the challenges for real-time biosensing and “edge” analysis? How do gold and gold-silver nanowires address the issue? How these sensors can implement elementary logic functions. Wearable ...

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are the ...

In the early digital era, logic gates were made exclusively of transistors and discrete components. The obvious occupation of a large space and increased heat dissipation pushed technology to ...

Overview of digital logic design. Implementation technologies, timing in combinational and sequential circuits, EDA tools, basic arithmetic units, introduction to simulation and synthesis using ...

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good. In the last ...
