The program is written in Visual Basic 6.0.
First, select whether you want the calculator to generate the capacitor
values for you or whether you want to enter them from a
file.
Internally generated capacitor values range logarithmically
from .1 to .001 uF with related inductance values ranging from
10 to .1 nH. The specific code used to generate the values is:
‘ user has entered nvalues, number of capacitor values
‘ user has entered nsame, number of caps of same value
For i = 1 To nvalues
C(i) = (0.1 * ((0.01) ^ ((i - 1) / (nvalues - 1)))) * 10 ^ (-6)
L(i) = (10 * ((0.01) ^ ((i - 1) / (nvalues - 1)))) * 10 ^ (-9)
Next i
For i = 1 To nvalues
Ctotal = Ctotal + C(i) * nsame
Next I
Use the file-input dialog to enter user-defined data. The input
file has provision for one or more “comment” lines, then a separator
between the comments and the data. The separator line
contains (only) the text “startdata” (w/o quotes.) Then there is
one line of comma-delimited text data for each capacitor value.
Each line contains (see sample, page 3):
Number of capacitors with this data
