You're too used to mathematics where that's Against the Rules -- this here be Style! I mean, if e e cummings can get away without caps in his _name_, for crying out loud, surely I can make such assertions? Perhaps you should re-read my post, ask yourself where the words "laser", "radar" and "snafu" came from, and note the case of the letters that I used. -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

Robot?? and they haven't gotten my address right either. after nearly 5 years. bastards. if they don't (or didn't) respect ol' e.e., they ain't gonna respect fred harris either.

Hmmm... but the "average RMS power" isJon - I don't think there is 'voltage decibel' and a 'power decibel'. There is just decibel. If you have voltage values to start with, then your conversion to dB uses a certain formula (20*log10) and if you have power values, you use another (10*log10). Perhaps, this separation in thought will help make things more clear for you.> expressed in dB(FS?) as well.

(my decapitalizations exist only in the cyber-slew.)You think you have trouble? There were once three different listings in the Brooklyn phone directory with my number. One was mine, and one was for somebody a few miles away. The third was for someone way out of the exchange area who happened to have the same name as an an acquaintance in Greenwich Village. (We had a bit of fun with that.) Jerry -- Engineering is the art of making what you want from things you can get. �����������������������������������������������������������������������
