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 ...

Cells of all organisms process numerous signals originating from the internal biological processes or from the environment to produce the appropriate cellular response. Designed gene regulatory ...

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 ...

This is going to be a column that’s divided into three sections. It’s based on a question that a student posed in the EEWeb forums, and he also sent it directly to yours truly. The core of this ...

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 ...
