Hello im trying to read 10 signals, the ADS1298 just have 8 channels, how can i read two more channels from ADS with "augmented leads" configuration? can you tell me where the signals come from?
Regards.
Hello Luis,
Thanks for your post!
Can you share a little information about your application?
Are you including the augmented leads within the 10 signal count? The augmented leads can be derived from Right Arm (RA), Left Arm (LA), and LL (Left Leg). This table sums it up nicely.
Additionally, this video on lead derivation may be helpful: https://training.ti.com/how-measure-ecg-analog-lead-derivation?cu=1128637
WCT is used to set a reference point for the chest leads. You set each of the different registers to a different primary lead (RA, LA, LL) and the WCT will derive the average point. This is then used to measure the different chest leads. Which channel is connected to which WCT amp will be dependent on your electrode configuration.
