This PRO Lesson describes how to design and develop software-based digital filters to perform a variety of physiological signal filtering tasks and cascade 2nd-order biquads to create high order filters. All data collection and analysis is done via the BIOPAC MP3X data acquisition unit and the Biopac Student Lab PRO software.
- Generate Filter Step Response signals.
- Generate the Filter Transfer Function.
- Verify the Filter Transfer Function using sine waves.
- Create a cascaded (dual biquad) filter to optimize the physiological recording of ECG.
Tasks Performed by the Student
- Review the template channels and, if desired, view parameters.
