The following filter options are provided:
|
• |
Off: Select Off to disable the filter. The historical information from previous transmissions ("pings") is not used to remove noise and unwanted echoes. |
|
• |
Weak: Select Weak to allow the filter to compare the echoes from the latest two pings. For the current echo to be shown, it must be present in both of these pings. |
|
• |
Medium: Choose Medium to compare the echoes from the latest four pings. For the current echo to be shown, it must be present in all of these pings. |
|
• |
Strong: Select Strong to allow the filter to compare the echoes from the latest eight pings. For the current echo to be shown, it must be present in all of these eight pings. |
The filters in the SN90 system are implemented in “series”. The Ping-Ping Filter is the last filter in the sequence, so any changes to the other filters may have an effect on how it works.
