In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...

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 ...

Analog circuit design guidelines. Digital circuit design guidelines. Differences in the guidelines between the two. Several products in the electronics industry require both analog and digital printed ...

A handful of CMOS logic chips is all it takes to build this versatile warning alarm. Discover a classic 1980 Elektor design ...
