Interactive Fourier Filter (Scripts) Publisher's description
from Tom O'Haver
A fourier filter for time-series signals.
A fourier filter for time-series signals. Version 1.5, May 4, 2007, is calibrated specifically for time-based signals. Does not require the Signal Processing Toolbox. By adjusting the parameters, you can create lowpass, highpass, bandpass, and bandreject (notch) filters with variable cut-off rate. There is an interactive version with sliders that allows you to adjust the filter parameters continuously while observing the effect on your signal dynamically. See:
for more information. (Thanks to Matthew Jones for the slider function.)
