Filter Processor Block
A filter block can be configured for each MVC input. The following functions are available:
• Insert — The filter block is inserted and made active by right-clicking on the block
and selecting from the context menu or by double-clicking and entering selections.
• Remove a filter — An active filter can be removed by right-clicking on the
block and selecting Delete or by selecting the block and pressing <delete> on the
keyboard. This sets the parameters back to default and bypasses the block.
•
Bypass — When bypass is active, signal flow passes through the
filter block without filter processing, regardless of the settings.
When bypass is removed, the signal will be processed according
to the filter settings. A red mark appears in the lower left of the
block (shown on the right) to indicate it has been inserted, but is
currently bypassed.
