Manual Filters
Manual filtering allows the user to select up to 3 filters and enter a low and
a high frequency for each filter. The user also can create filters by
selecting (clicking and dragging) areas on the Spectrum graph.
Auto Filter
Auto filtering attempts to select the optimum filter settings. The Auto
filter mode can often provide very good results. However, in certain cases,
manual control of the filtering may be required. ADS does not
recommend using Auto Filter with Hydrophones.
After choosing the Auto radio button, selecting the Apply button applies
auto filtering to the correlation display. Please note that auto filtering may
take some time. When the auto filter process is complete, the dialog box
shows the filters that have been selected automatically by the software. If
necessary, the user can cancel the auto filters and change the filter values
manually.
General
This section allows the user to select various filter options.
