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 ...

The myriad processes occurring in biological cells may seem unbelievably complex at first glance. And yet, in principle, they are merely a logical succession of events, and could even be used to form ...

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 ...

We have a bit of a love/hate relationship with tools in the web browser. For education or just a quick experiment, we love having circuit analysis and FPGA tools at our fingertips with no installation ...

Fig 1. A typical CMOS input circuit comprises a “P” and “N” transistor. One is fully “on” for logic high, and the other is “on” for a logic low. Fig 2. When a CMOS input pin is at logic high or low ...

Living cells make decisions based on information processing genetic programmes. Many of these programmes execute digital functions 1,2,3,4,5,6,7,8. The capability to build synthetic digital systems in ...

Engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell's DNA and passed on for dozens of ...
