Fetal electrocardiogram (FECG) signal processing is a critical area of research aimed at monitoring the heart activity of a fetus during pregnancy. This non-invasive technique involves extracting ...

A signal averaged ECG is a diagnostic test that averages multiple QRS complexes over a 10-minute time period, or at least 250 QRS complexes in order to see minute changes in the electrical ...

The differential signal then goes through a low-pass filter to remove high-frequency noise, after which it enters an ADS1291 ECG analog front-end chip. The ADS1291 contains a delta-sigma analog-to ...

[Ultimate Robotics] has been working on designing and producing an extremely small ECG that can stream data ... at these sample rates and filtering the signal of unwanted noise the device draws ...
