Re: [DUG]: db calculation

[Ross Levis]

Yes, I see.  However, how does one do ^ in delphi.  I'm use to this in other languages but Delphi thnks it is a pointer.

Cheers,
Ross.

This formula doesn't seem to work.  The 20 should be 10 as Neven pointed 
out but I believe a -3db reduction should take 65535 to 32767 but it's 
not close.  Any ideas?
    

i read your "log" to be "natural log" but after reading
Neven's post I think it's probably base 10 logs so my
"exp()"   should be 10^ instead

P1 = P2 * 10^(db/10)
