Notch Parameters Section
•
Notch Active
This check box activates or deactivates the generation of a notch in the
equally spaced Multi-Tone signal.
•
Start Tone
It is the index of the first tone to be removed in a notch. Acceptable
indexes start with 1.
•
Stop Tone
It is the index of the last tone to be removed in a notch. Acceptable
indexes start with 1.
•
Center Frequency
It is an indicator only. The central frequency for the notch is computed
and shown in this field.
•
Span
It is an indicator only. The tone-free frequency span for the notch is
computed and shown in this field.
Arbitrary Tones Section
Alternatively, an edition table is displayed for arbitrarily spaced tones
definition ("Arbitrary" selected in the Tone Distribution drop-down list).
When not previously edited (or empty), the table is automatically loaded
with the parameters of the tones defined in the equally spaced tone
section. This allows for easy edition of individual tones or the creation of
multiple notches, or both. Parameters for each tone include its frequency
(in Hz), its relative amplitude (in dB), and phase (in degrees). Entries in the
table may be added, edited, and deleted. Entries in the table may be also
sorted in ascending or descending order of any parameter by clicking in
the corresponding field name.
Addition of a new entry in the table can be done by editing the empty
edition field located at the bottom of the table. Deletion of any number of
entries can be performed by selecting the ones to be deleted and then
pressing the [Delete] key of the keyboard. Meaningful numeric values must
be typed into the edition fields. Otherwise, an error can be generated.
While a valid frequency entry must be always entered, any of the
amplitude and phase edition fields may kept empty so they take the
default values (0.0 dB for Amplitude and 0.0 degrees for Phase).
