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.

A “cheap as chips” open-source Analog Computer can run circles around a Raspberry Pi in solving differential equations and for simulating natural phenomena. To keep costs down, the Anabrid team ...

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 ...

We live in an analog world of continuous information flow that is both processed and stored by our brains at the same time, but our devices process information digitally in the form of discrete binary ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

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 ...

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.

The complexity of integrated circuit (IC) design has expanded a billion-fold since the invention of the first transistor, guided by the famous “Moore’s Law” of the semiconductor world. An important ...
