The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic ...

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 ...

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 ...

Digital transition switching is the primary cause of noise in mixed-signal devices. Signal noise and immunity to power, ground, and substrate noise all benefit from using differential circuits. Design ...

Why You Can’t Just Use a Spectrum Analyzer Industry has an increasing demand for spectrally pure signals in applications such as imaging radar, mobile communications, satellite communications, weather ...

If you want to extract a signal from a huge amount of noise, a lock-in amplifier is the ideal tool. But when it comes to buying one, doing your homework first can avoid a costly mistake, advises ...

Patrick Flandrin president of the association GRETSI. The notion of “signal processing” might seem like something impenetrably complex, even to scientists. However, the fact is that most of them have ...
