An analog computer is a system that provides information in continuous form. These computers can only represent physical quantities such as pressure, weight, voltage pressure, speed, and more.

Lately, many electronics observers rave over massive digital chips, and for a good reason. Incredible things happen when billions of tiny transistors, each a few nanometers wide, work together. These ...

The rapid evolution of electronic system design has underscored the importance of Field Programmable Analog Arrays (FPAAs) and mixed‐signal systems in achieving flexible, energy‐efficient processing.

At one time a scientist or engineer trying to solve a tough problem with electronic computation had the choice of an analog computer, a digital computer, or both together in a hybrid configuration.

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 ...

When you think of analog computing, it’s possible you don’t typically think of FPGAs. Sure, a few FPGAs will have specialized analog blocks, but usually they are digital devices. [Bruce Land] — a name ...

The analog computer of decades-gone-by is something many of us younger engineers never got the chance to experience first hand. It’s pretty much a case of reading about them on these fine pages or ...

Millions of qubits—rather than the few hundred that are currently possible—are required for quantum computers to achieve their full potential. However, the path toward quantum computer scaling is not ...

Simulations of quantum many-body systems are an important goal for nuclear and high-energy physics. Many-body problems involve systems that consist of many microscopic particles interacting at the ...

Q: My Boston Acoustics BA735 digital speakers came with a previous computer, but I’d like to connect them to my MacBook Pro. The speakers and the Mac both use the same 3.5-millimeter jack system, but ...
