I am creating a lowpass Butterworth filter using FDATool. I export the filter to the workspace, open SPTool, and import the filter. When I view the filter, the frequency axis for the magnitude response is incorrect. This seems to be due to the fact that some of the filter specifications have not been imported.
MATLAB: Are settings saved incorrectly when I import a filter from FDATool to SPTool using the Filter Design Toolbox 3.1 (R14SP1) and the Signal Processing Toolbox 6.2.1 (R14SP1)
