Microsoft has built a prototype computer that uses light and analog signals instead of traditional binary computing.

Recent progress on both analog and digital simulations of quantum fields foreshadows a future in which quantum computers ...

One great example of analog vs digital methods is reading an arbitrary analog quantity, say a voltage, a temperature, or a shaft position.

Today, most of what we think of as a computer uses digital technology. But that wasn’t always the case. From slide rules to mechanical fire solution computers to electronic analog computers, … ...

Here is another little analog computer example. Instead of the 100-kΩ resistor going from the summing point of A4 to the output of A3, we could have a 50-kΩ resistor going to the tap of a 50-kΩ ...
