Description of controls is as follows:
Display Block: Used to select the General Filter stage whose coefficients are to be displayed
via the Filter combo box; available options depend upon the System
Bandwidth and Input Mode settings. Also, the Number of Coefficients to
be displayed can be specified; options are power-of-two steps from 32 up to
the Filter Size as specified in the control window for the filter.
Marker Block: Used to turn the vertical red marker in the Coefficient Display area on and off
via the Marker button; GREEN LED indicates the marker is on, LED OFF
indicates the marker is off. The marker allows Time, Coefficient number, and
Value readout of any coefficient in the filter. Also, the Show Grid checkbox
can be used to turn the grid markings on and off as needed for viewing the
impulse response curve most clearly.
To move the marker, simply click and/or drag the mouse cursor to any desired
point within in the Coefficient Display area. The Coefficient Display area will
"pan", or shift, left or right whenever the marker selects a coefficient that is
outside the displayed area; click on the left or the right side of the Coefficient
Display grid to pan left or right. Clicking the Find Peak button instantly moves
the marker to the largest magnitude in the Spectrum Display. Alternatively,
