If you have had trouble with ordinary calculus, you may not be pleased to hear about “photonic calculus” — a recent idea from [Nader Engheta] of the University of Pennsylvania. The idea is that ...

Today, most of what we think of as a computer uses digital technology. But that wasn’t always the case. From slide rules to mechanical fire solution computers to electronic analog computers, there ...

Hardware interfaces that accept non-digital signals. For decades, all the plugs and sockets on traditional audio and video equipment connected analog lines. In addition, the common high-density DB-15 ...

In the first of three parts, Andy hypothesizes that the K2-W Analog Computer Op Amp’s design has some unrevealed mad science in its input-stage design. 1. K2-W Op Amp schematic from Bob Pease’s ...

This file type includes high-resolution graphics and schematics when applicable. 1. Bob Pease built this varactor-input op-amp out of discrete components, based on an old design of Jim Williams. A ...

Makers and computer enthusiasts interested in building their very own analogue computer, may be interested in a new modular analogue computer kit showcased by the grappendorf.net website this week.

The standard analog input for a PC monitor is the Video Graphics Array connection. As technology has developed, many PC monitors have been manufactured accommodate multiple input standards. While VGA ...

The ADS5400 is a 12-bit, 1-GSPS analog-to-digital converter (ADC) that operates from both a 5-V supply and 3.3-V supply, while providing LVDS-compatible digital outputs. The analog input buffer ...

A 50 percent reduction in size provides greater packing density for this certified failsafe I/O, which also has six isolated Hart analog inputs between channels and its backplane bus. It supports ...

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 ...
