The creation of the clipping domain has been completed. Its starting
point is determined by the current position of the second coupling echo.
The process has been recalculated.
The first layer interface echo protrudes from the blocked domain. That’s
why it will be extracted. All further echoes are located within the
blocked domain. For that reason, they will not be extracted.
Now a suitable clipping domain for the second layer interface echo is to
be created.
Press Help/Extras menu to call the requested submenus.
Position the cursor behind the first layer interface echo pulse. The point
at which the pulse penetrates the edge of blocked domain (see the
arrow) must be located left to the cursor. Make sure the amplitude limit
is set in a way the second layer interface echo protrudes.
Press OK to confirm.
The second clipping domain has been created and the process has
been recalculated. Now the second layer interface echo will be
extracted correctly.
You can clearly see the second clipping domain precisely starts at the
above mentioned point of penetration of the first echo pulse. If during a
new measurement, the first layer interface echo changes its position,
the starting time of the second clipping domain will move accordingly.
This adaptive behaviour represents the key advantage of this clipping
method.
For clarification, the procedure has been repeated for the second layer
interface echo (though the suppression effect was already good
enough). The amplitude limit has been set to a highly negative value in
order to suppress any subsequent interferences.
Also the second layer interface echo clearly shows the third clipping
domain exactly starts at the point where the echo pulse penetrates the
edge of blocked domain.
