Learn how ECG noise filtering that adapts to noise type improved QT and QRS accuracy and supports more reliable cardiac ...

White noise is a random signal with equal power across frequencies, commonly heard as static, and widely used in acoustics ...

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 ...

Magnetotellurics is a key geophysical method that exploits natural electromagnetic fields to probe the Earth’s subsurface, offering invaluable insights into lithospheric structure and resource ...

Optical signal processing and performance monitoring are pivotal in advancing high‐speed communication systems by enabling precise analysis and real‐time management of signal quality. By utilising ...

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 ...

A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...

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 ...
