ECG high pass filter when connecting to third party devices

Postby BITalino » Mon Jan 13, 2014 11:07 am

Depending on your target application, when connecting the BITalino ECG sensor to a third-party device you may want to use a high-pass filter to remove the baseline wander due, for example, to respiration. The following figure shows a simple RC circuit for a 5Hz high-pass filter.
