By removing some frequencies, the filter creates a smoothing effect. That is, the filter produces slow changes in output values to make it easier to see trends and boost the overall signal-to-noise ratio with minimal signal degradation. Low-pass filters, especially moving average filters or Savitzky-Golay filters , are often used to clean up signals, remove noise, perform data averaging, design decimators and interpolators, and discover important patterns.

Other common design methods for low-pass FIR-based filters include Kaiser window , least squares , and equiripple. Of particular interest is the built-in filter visualization tool, which you can use to visualize, compare, and analyze different filter responses.
