This graph appears to be labeled incorrectly. The x axis says the units are in Hz but they appear to actually be kHz.

File format

JPEG is about the worst possible format for a line diagram like this. If a vector format isn't possible, but a high resolution original is available, it really needs to be rescanned in a lossless format with as much resolution as possible. David Woolley (talk) 22:05, 15 September 2010 (UTC)
