Electrocardiogram (ECG) signal compression techniques are essential for the efficient storage, transmission and real‐time processing of cardiac data. Advanced methods utilising discrete wavelet ...

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 ...

Electrical engineers generated short, powerful light pulses on a chip -- an important step toward the optical interconnects that will likely replace the copper wires that carry information between ...

The signal in Figure 1 originates in a pristine state at its transmitter. After passing through a long coaxial cable, high-frequency losses within the cable round off the signal edges, making each ...
