Contemporary logic circuits use MOSFETs as the elements to build gates, but there are many ways to implement them. Using relays is one of them, and you can literally see how they work.

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 ...

When pulsed at their inputs, they change their state. To learn how gates work in a circuit, see Boolean logic. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

A PWM-controlled regulator, this time using a logic gate IC, op-amp, and resistors and capacitors to buffer the PWM signal.

simple circuit to behave like any kind of logic gate. Such a chip could be transformed, for example, from a graphics card into a memory chip and back again – in just two computer clock cycles.

Researchers have engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations. A team of UCSF researchers has ...
