Using the ADS1298ECG-FE Software

www.ti.com

The low-pass filter controls a digital low-pass filter, whose order and cutoff frequency are controlled

using the Filter Order and Cutoff Freq controls in the low-pass filter part of the Post Processing

Filters group (left side of the box).

The notch filter provides a 50Hz/60Hz notch filter, whose order and 50Hz/60Hz notch selection are

controlled using the Filter Order and Notch Freq controls in the low-pass filter part of the Post

Processing Filters group (center of the box).

The high-pass filter controls a digital high-pass filter, whose order and cutoff frequency are

controlled using the Filter Order and Cutoff Freq controls in the high-pass filter part of the Post

Processing Filters group (right side of the box).

NOTE: The digital filters are not part of the ADS1298. These are digital filters implemented in the UI

to aid in the evaluation of the ADS1298ECG-FE.

4 - Zoom Feature

The zoom feature is available to allow the user to navigate and view all signals at the same time, as

shown in Figure 28. This tool allows the user to zoom in/out on the horizontal or vertical axis and pan

left or right while viewing all ECG signals simultaneously.

Figure 28. ECG Signal Zoom Feature for Six Leads

Additionally, each ECG signal can be zoomed individually by moving the mouse (which appears as a plus

icon) over the lead of interest and clicking on it. A new window opens showing the raw ECG data as read

from the ADS1298. This window provides controls in the lower right corner to zoom in/out or pan right/left

to provide a more detailed inspection of the individual ECG signal.
