AV in Signal Lab

These components are hidden Jewels for Delphi!  I was playing around
with Signal Lab in D7.  If I create a simple demo with 2 tones
mulitiplied, do the FFT then hook Power Spectral Density on to the FFT
if I set the Plot viewing the Power to log it will AV.

Thanks,
Jim

Thank you!
Reproduced and Fixed :-) .
If you need to get this fix before the next release, please contact me directly. I will be out of the country for 25 days starting this Friday, and I expect to get a new release couple of weeks after I get back.

Good.  Do one more thing.  Add another check box and add this:

SLRandomGen1.Enabled := CheckBox2.Checked;

Label it "Enabled Noise".  

Now in the OI for the SLRandomGen1 set Enabled to FALSE.

No run it.  The result is what I expect, a 20Mhz tone with side bands
at 15Mhz and 25Mhz.  Now click the new checkbox.  Where did the 20Mhz
tone go?  I should not have disappeared. Now uncheck the box.  The
"correct" result is not gone until you close and restart the app.

Hi Jim,

Thank you!

Please if you discover bugs, contact me directly, as I don't always check the newsgroups, and react faster over e-mail.
If you need the fixes, please contact me ASAP, as I will be out of the country for 3 weeks, and may not be able to get you update for that period.
Cheers,
  Boian
