To find a magic sinewave:
FIRST, use the scrolling menu to select the type of Magic
Sinewave desired.
By AMPLITUDE:
Enter the desired amplitude from 0.00 to 1.00
into the Target Amplitude box. Then click on
Set Amplitude. A
good guess for a magic sinewave solution should appear. Next
click on Improve to do the actual magic sinewave optimization.
Several clicks may be required for extreme accuracy.
By POWER: Enter the desired power from
0.00 to 1.00
into the Target Power box. Then click on
Set Amplitude.
A good guess for a magic sinewave solution should appear. Next
click on Improve to do the actual magic sinewave optimization.
Several passes may be required for extreme accuracy.
Amplitudes near 1.0 for very large n may not converge.
Instead, "sneak up" on the problem by using Improve
from a nearby lower working value rather than reinitializing
and reguessing
with Set Amplitude.
The InstaCalc buttom combines amplitude or power settings
with six iterations of improvement.
To analyze a possible magic sinewave:
By ANGLES: Enter or alter the desired start and ending angles
for each pulse in their respective boxes. Then click on Set
Angles. An analysis of the funamental amplitude and power
will appear, along with the harmonic strength of the first
113 harmonics. Angles are limited to the first quadrant and
must not overlap. The start angle must always be less than
the stop angle as well.
To explore data table quantization effects:
Optimize the magic sinewave. Then click on ONE quantization
button to view the attainable distortion. Always reoptimize before
changing your quant selection. Quantization values are only a
guideline approximation.
To export angle or pulse data values:
Cut and paste from their respective Export areas. Present format
is in the PostScript language. This can be customized.
