Analog signals are structured, created, transmitted, and interpreted for the use of analog equipment. Digital signals do the same for use with digital equipment.

These analog quantum simulators are designed to solve problems that even the fastest, most efficient digital quantum computers can’t. But we aren’t talking about room-sized computers like you ...

By the 1970s, the analog-digital difference could be summarized like this: The last factor was a big deal, as the accuracy of analog computers was always limited by their components.

Because digital computers were unsuitable for more complicated applications, such as aircraft flight simulators and synthetic-aperture radar, analog computing (and hybrid computing) remained the ...

The inherently analog nature of the system means that computation occurs at the speed of electromagnetic waves as signals propagate through the network. This is in stark contrast to digital computers, ...

The future of computing may be analog. The digital design of our everyday computers is good for reading email and gaming, but today's problem-solving computers are working with vast amounts of data.

John Vincent Atanasoff and Clifford E. Berry designed the first digital computer in 1942. The computer would accept two linear equations at a time with up to 29 variables and a constant.

It was rarely done. But as digital computers got faster, it soon became apparent they were going to give analog computers some competition.

We have to wonder, if digital computers didn’t work out, what the state of the art would be today in analog computing. After all, we had an analog laptop in 1959. Sort of.
