Re: "I'm an Engineer and You're Not".......

Todd, Soundmind attacks at what he considers 'chinks in our armor' much like my dad did with me when we were discussing politics. My dad would always 'wave the flag' and say: "Are you for or against me?" What a waste of energy. :-(
In my case: I have a degree in Physics with a minor in electronic engineering. Therefore, I have not taken each and every course that Soundmind may have taken, but I went back to university after several years of practical experience in electronics engineering, to get what I missed. Sometimes, as I tried to explain to Soundmind, I seem to have unconventional definitions of what has been apparently standardized by the engineering society (I have been a full member of the IEEE for more than 40 years, but that doesn't seem to count) and for this, I have been criticized by some engineers as not knowing 'engineering concepts'. This is nonsense! Soundmind criticized me for saying that the risetime is ambiguous, when the low pass filter type and number of poles in the rolloff is not known.
Well, there really is a difference between an 'ideal brickwall filter' and an early elliptical filter used by CD players.
For the record, a simple 6-12dB rolloff is best.
