Origin offers an FFT filter, which performs filtering by using Fourier transforms to analyze the frequency components in the input dataset.
There are six types of filters available in the FFT filter function: low-pass, high-pass, band-pass, band-block, threshold and low-pass parabolic. Low-pass filters block all frequency components above the cutoff frequency, allowing only the low frequency components to pass. High-pass filters work in the opposite way: they block frequency components that are below the cutoff frequency.
This tutorial will show you how to perform the low-pass and band-pass filtering using Origin's FFT filter.
