Analog Computing for the 21st Century. Bernd Ulmann. Many people think of analog computing as a historic dead-end in computing. In fact, nothing could be further from the truth as analog computing - together with quantum computing - has the potential to bring computing to new levels with respect to raw computational power and energy efficiency.

Conventional digital computers are struggling to keep up. An analog optical neural network could perform the same tasks as a digital one, such as image classification or speech recognition, but because computations are performed using light instead of electrical signals, optical neural networks can run many times faster while consuming less energy.

Engineers began using the word analog in the 1940s (shortened from analogue; they like compression) to refer to computers that simulated real-world conditions.But mechanical devices had been doing ...

Electronic analog computers developed in the mid-20th century operated by manipulating potential differences (voltages). Their basic component was an operational amplifier, a device whose output current was proportional to its input potential difference. By causing this output current to flow through appropriate components, further potential differences were obtained, and a wide variety of ...
