The plugin have the following input paramters:
Gaussian filters are important in many signal processing, image processing, and communication applications. These filters are characterized by narrow bandwidths and sharp cutoffs. A key feature of Gaussian filters is that the Fourier transform of a Gaussian is also a Gaussian, so the filter has the same response shape in both the time and frequency domains.
- The cutoff parameter defines the filter cutoff-frequency.
- The DC-level parameter defines the height of the dc-center component.
