Yes yer mistaken.. but it's an easy mistake to make. Since the random
output voltage swing probably isn't that high at max (uhm, 3v or so? I'm
just guessing) you might not really hear the difference between v/octave
response and v/hz response over such a small scale. The higher up on the
v/hz scale you get, the less linear it is, because it's an exponential
system. Dig? :)
