The previous article examined the concept of logic gates. They can be made from discrete and active electronic components, although today logic gates are available within integrated circuits. In this ...

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computations ...

Find out how a digital technique performs multiplication on two bitstreams and avoids the cost of the analog multiplier.

The idea of making DNA perform computational tricks is hardly new. These data-packed molecules are in many ways perfect for the job. One very public test of their potential came in 1994, when Leonard ...
