A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

When the phrase ‘analog to digital conversion’ is used, we tend to assume that the conversion is taking something continuous like sound or video and making it discrete so that digital computers can ...

What is analog computing and how is it used? What is digital computing and how is it used? Why both methods provide promising results, depending on the application. The unveiling of intelligent ...

Researchers at Cornell University have developed an electronic chip that they describe as a "microwave brain." The simplified chip is analog rather than digital, yet can process ultrafast data and ...

(Nanowerk Spotlight) The pursuit of faster and more efficient computing has been a driving force in technological progress for decades. As the demand for computational power continues to grow, ...

My first job out of college was testing and debugging control loading systems on flight simulators for 747 and the “new” 767 airliners. In the late 1970s, the control loop that simulated the feel of ...

If you've ever taken a look at the back of your computer, you've no doubt seen the rainbow of holes that make up the different audio ports your motherboard has to offer. You'll also spot many of the ...

Our new tech editor for Analog looks at the evolution of “analog” and how it inadvertently spun off a pop music genre. Operational Amplifiers are exactly that—amplifiers that can perform mathematical ...

Analog vs. Digital: What’s the Difference? Air temperature, sound loudness,light intensity—in nature, all of these quantities vary smoothly and continuously over a range. Such quantities is called ...

You don’t need 0s and 1s to perform computations, and in some cases it’s better to avoid them. Computing today is almost entirely digital. The vast informational catacombs of the internet, the ...
