Designing a Floating-Point Filter (Digital Filter Design Toolkit)

This tutorial introduces you to the basics of designing a floating-point filter by using the LabVIEW Digital Filter Design Toolkit. In this tutorial, you will design a lowpass Butterworth filter. This filter passes frequencies below 100 Hz with a maximum ripple of 0.1 dB and attenuates frequencies above 200 Hz with a minimum attenuation of 60 dB. This filter is suitable for filtering electrocardiograph (ECG) signals.

This tutorial consists of the following three parts:

• Part 1: Entering Floating-Point Filter Specifications
• Part 2: Analyzing a Digital Filter
• Part 3: Using a Digital Filter

Note  Refer to the labview\examples\Digital Filter Design\Getting Started\Tutorials\ directory for completed versions of the digital filter you create in this tutorial.
