H20 Filtering

View Cart “General-purpose Electrodes” has been added to your cart.

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.

Experimental Objectives

  1. Generate Filter Step Response signals.
  2. Generate the Filter Transfer Function.
  3. Verify the Filter Transfer Function using sine waves.
  4. Create a cascaded (dual biquad) filter to optimize the physiological recording of ECG.
