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 ...

Real-world signals, such as vibration, temperature, pressure, and light, require accurate signal conditioning and signal conversion before further data processing in the digital domain. In order to ...

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 ...

Photonic analog-to-digital conversion (ADC) represents a paradigm shift in signal processing by leveraging the inherent advantages of photonic devices to digitise analog signals. The approach aims to ...

The design and optimisation of analog-digital converters (ADCs) and digital-analog converters (DACs) play a pivotal role in modern electronic systems, bridging the gap between the analog real world ...

A signal chain consists of several components, such as amplifiers, data converters, interface, clocks and timing. The purpose of the signal chain is to gather and process data or apply system controls ...

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 ...

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 ...

CHELMSFORD — “Inventor” is Albert Jean’s middle name. For many years, the Dracut accountant has captured analog TV signals through a V-shaped, tinfoil-covered antenna he made from scratch. The device ...
