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 ...

The electrocardiogram (ECG) remains a cornerstone in cardiovascular diagnostics, yet its clinical utility is often compromised by signal distortions introduced during acquisition. Contemporary ...

The expanding use and importance of image sensors in safety-critical applications such as automotive and medical devices has transformed noise from an annoyance into a life-threatening problem that ...

The notion of “signal processing” might seem like something impenetrably complex, even to scientists. However, the fact is that most of them have already being doing it for a long time, albeit in an ...

Many noise sources can plague high-speed radio-frequency (RF) analog signal chains, making design considerations that much more challenging. Both megahertz and sub-terahertz sampling-rate converters ...

Dr. Blough’s research includes dynamic measurement problems, developing new digital signal processing algorithms to understand NVH type problems and ways to improve the NVH characteristics of ...
