Vertical Integration Filter

Use the Vertical Integration option to apply a Fast Fourier Transform (FFT) vertical integration filter to a channel.

The filter option is available with the following extensions and menus:

• 1D FFT > 1D Filtering
• Moving Platform Gravity  > Filters > Apply Single FFT Filter

Vertical Integration filter options

There are no user-defined parameters for this filter.

Application Notes

• Calculates the vertical integral of the input transform.

• This operation is the inverse of the vertical derivative.

• The zero wavenumber is set to 0 to avoid undefined values.

Filter Formula

L(ω) = ω ^-1
