DNA has been used as a building block to construct a series of complex logic circuits to perform nonarithmetic functions, including a multiplexer, demultiplexer, encoder and decoder. This is the first ...

Biochemical circuits made of rationally designed DNA molecules are proofs of concept for embedding control within complex molecular environments. They hold promise for transforming the current ...

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 ...

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 ...

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 ...

In the ongoing drive to make circuitry ever smaller and more powerful, researchers in Canada have taken things to a very small extreme. They devised a method for turning individual silicon atoms into ...

March 29, 1961 - LOGICAL microcircuits in transistor cans are now being offered by four major companies. Heavy research and production is being pressed by Fairchild Semiconductor Corp., Raytheon Co., ...
