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.

Analog computers have been used extensively in the past, for things like tide calculations, but in the semiconductor era things have mostly gone digital. Even where you have analog elements, like DRAM ...

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 ...

In 1961, the best general purpose desktop computer money could buy was the Pace TR-48. At just 400 pounds and $25K, the only downside was that it was a little tough to program. That's because the ...

The rapidly-improving speed and versatility of digital computers has mostly driven analogue computers out of use in modern systems, as has the relative difficulty of programming an analogue computer.

Successive approximation register analog to digital converters, better known as SAR ADCs, are a versatile class of analog to digital converters that produce a digital discrete time representation of a ...

Today's analog system designers face many design challenges. Not only do designers need to select the proper integrated-circuit components, but they also must accurately predict the interactions of ...

All analog-to-digital converters (ADCs) have a certain amount ofinput-referred noise. In most cases,less input noise is better. There are some cases, however, where inputnoise can actually be helpful ...

A key subsystem in a programmable logic controller is the analog input module, which provides a high-precision front end to measure a wide variety of sensors. In many cases, however, the amplifier ...
