The binary number system was refined by Gottfried Wilhelm Leibniz (published in 1705) and he also established that … See more

An advantage of digital circuits when compared to analog circuits is that signals represented digitally can be transmitted without degradation caused by noise. For example, a continuous audio signal transmitte… See more

A digital circuit is typically constructed from small electronic circuits called logic gates that can be used to create combinational logic. Each logic gate is designed to perform a function of Boolean logic when acting on lo… See more

Engineers use many methods to minimize logic redundancy in order to reduce the circuit complexity. Reduced complexity reduces component count and potential errors and therefore typically reduces cost. Logic redu… See more

Digital design started with relay logic which is slow. Occasionally a mechanical failure would occur. Fan-outs were typically about 10, limited by the resistance of the coils and arcing on the contacts from high voltages.
Later, … See more

In 2009, researchers discovered that memristors can implement a Boolean state storage and provides a complete logic family with very small amounts of space and power, using familiar CMOS semicondu… See more
