In the modern era, advancements in implantable cardiac monitors are revolutionizing the landscape of cardiac healthcare. These sophisticated devices, designed to continuously track heart activity, are ...

[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 ...

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 ...
