Back in the day where the microprocessor was our standard building block, we tended to concentrate on computation and processing of data and not so much on I/O. Simply put there were a lot of things ...

Optical or magnetic sensors for position and angle sensing in motion control systems generally provide sine and cosine signals for conversion. The 90° phase shift between sine and cosine allows ...

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

In previous installments of the AudioFile, we've talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We've also discussed the process of ...

Level-crossing analog-to-digital converters (LC-ADCs) represent an innovative approach to signal digitisation that departs from conventional uniform sampling. Instead of capturing signals at fixed ...

Confused by analog-to-digital converter specifications? Here's a primer to help you decipher them and make the right decisions for your project. Although manufacturers use common terms to describe ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Follow these seven steps to successfully select a photodiode sensor and design an analog front end for a range of applications such as optical communications and light-based measurements. The energy ...

Several microcontroller applications utilize a digital-to-analog converter. Though many of these applications require a complex DAC, some may only need a simple single-channel DAC. Because most MCUs ...
