There are four sub-group parameters in the equation editor plus
control buttons and equation field. These parts are described below.
Anchor
The anchors define start and end point of which the equation will be
generated. By default the anchors are placed at the start and the
end of the horizontal (time) scale however, the equation can be
limited to a specific time scale by moving the anchor points from
their default locations.
Start – defines the first point where the created wave will start. Note
that if you change the start point the left anchor will automatically
adjust itself to the selected start point.
End – defines where the created waveform will end. Note that as
you change the end point the right anchor will automatically adjust
itself to the selected end point.
Waveform Amplitude
The vertical axis of the Wave Composer represents 14-bits of
vertical resolution. That means that the equation is computed,
resolved and generated with 1/32,768 increments and accuracy.
The Waveform Amplitude fields in the Equation Editor are used in
two cases: 1) when the “amp” parameter is used in the equation or
2 if the Level Adjuster is set to Auto. Information on these two
operations is given later.
Max – defines the positive peak of the vertical axis
Min – defines the negative peak of the vertical axis
Cycles
The Cycles parameter defines how many waveform cycles will be
created within the specified start and end anchor points.
Level Adjuster
The Level Adjuster is a convenient tool that helps you adjust the
amplitude and offset without modifying your equation. The Level
Adjuster mode does not interfere with your calculations and
displays the waveform as computed from your equation. The only
difference is that your final calculations are stretched or shrunk or
offset on the vertical scale to fit the new amplitude and offset
boundaries.
If you change the Max and Min setting in the Waveform Amplitude
fields and press the Adjust key, your waveform will offset
immediately without changing the equation. The same way, you can
also change amplitude only or both amplitude and offset. If you
check the Manual option, you’ll have to click on the Adjust button for
the Waveform Amplitude parameters to take effect. The Adjust
button name will change to Restore and back to Adjust if you click
on it again. If you check the Auto option, your waveform will be
created automatically with the new Amplitude setting.
