Start Phase
– The start phase parameter defines the angle of which
the sine will start. The example shows 0
°
start phase.
Power
– Sine to the power of 1 will generate a perfect sine. Power
range is from 1 through 9.
Generating
Waveforms Using
the Equation
Editor
One of the most powerful feature within WaveCAD and probably the
feature that will be used most is the Equation Editor. The Equation
Editor let you write equations the same way as you would do on a
blank piece of paper. The equations are then translated to sequential
points that form waveforms and are displayed on the waveform
screen. The Equation Editor will detect and inform you on syntax
errors and, with its self adjusting feature, will automatically adjust your
parameters so that none of the points on your waveform will exceed
the maximum scale limits.
When you invoke the Equation Editor, the dialog box, as shown in
Figure 4-27 will display. Use the following paragraphs to learn how to
use this dialog box and how to write your equations.
Figure 4-26 The Equation Editor Dialog Box
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.
