Pulse oximeters, a type of photoplethysmography (PPG) sensor, are electronic devices that measure a person’s blood-oxygen saturation (SpO 2) and heart-rate (HR) levels. Since their inception in the ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240009 , discusses a smart photonic wristband for pulse wave monitoring. Pulse waves are a prominent component of physiological ...

Detecting a signal pulse is usually basic electronics, but you start to find more complications when you need to time the signal’s arrival in the picoseconds domain. These include the time-walk effect ...

Atrial fibrillation (AF) represents a complex disorder of cardiac rhythm, deeply rooted in the intricate interplay between molecular, cellular, and ...

Radar is a remote sensing technique used to detect, locate, and analyze objects by emitting electromagnetic waves, more specifically microwaves, and measuring the time interval between the ...

Chapter 11 of this book “Digital Data Locked Loops“ is being made available as a series of design articles. The first part is available here. I have spent more than 30 years toil.ing away as a digital ...

Digital-to-analog converters (DACs) have been widely used since the 1980s in arbitrary function generators (AFGs) and arbitrary waveform generators (AWGs) to produce signals for verification, ...
