Gaussian Filter

This no_std library provides Gaussian filter design.

Filters may be designed by a known sigma or a known cutoff frequency and sample rate.

Orders 0 through 3 are supported.

Structs

GaussFilt1D

Iterator for applying a Gaussian filter to a 1D signal. This is the iterator returned by apply_gaussian_filter1d.

Functions

apply_gaussian_filter1d

Gaussian filter a signal, using a prepared filter.

design_gaussian_filter1d

Design a Gaussian filter with a known sigma. The filter is symmetric and will be sized based on the standard deviation and truncation.

design_gaussian_sigma_for_cutoff

Choose a sigma based on a cutoff frequency and sample rate.
