<DIV>Hi again,</DIV>
<DIV> </DIV>
<DIV> I bought a bunch of Bourns 300K panelmount pots for a great deal (50 cents each!) I figured, hell...I'll use these in place of the typical 100K attenuator pots. I read something about a higher resistance results in higher noise. I don't know where I read that, or if it's actually true.</DIV>
<DIV> Couple days ago I was using this: <A href="http://www.mindspring.com/~clist/PotGraph.html">http://www.mindspring.com/~clist/PotGraph.html</A></DIV>
<DIV> </DIV>
<DIV>To my dismay, I found if I use 300K pots I'll get a response closer to exp(log?) than linear. Bummer. Then I checked 100K pot into 100K input resistor and the response is in the middle of log and linear response. Surprising. It seems the ideal attenuator pot value for 100K impedence is a 10K pot. Shouldn't this value be the standard as opposed to 100K or 50K pots for true linear response.</DIV>
<DIV> </DIV>
<DIV> What do you think? Am I missing something? </DIV>
<DIV> </DIV>
<DIV> BTW the 300K are good for audio mixer attenuators with the 100K impedence (oh...and the fine tune on my VCO cause it connects to a 3.3M resister, check the graph).</DIV>
<DIV> </DIV>
<DIV>Thanks for reading,</DIV>
<DIV>P.v3</DIV><p>
