The standard word "paris" has 48 elements.  That makes the baud rate
for CW (48/60) x WPM or 0.80 x WPM.

ITU defines the "Necessary Bandwidth" for CW as 3 or 5 times the speed
in bits per second (baud rate) where 3 x is for "non fading circuits"
(where the waveform does not need to be so "sharp") and 5 x for "fading
circuits."    See:
     http://http://life.itu.ch/radioclub/rr/ap01.htm part B.
The same table is found in Title 97, Part 2 of the Code of Federal
Regulations (FCC Rules) as §2.202(g)

The constant 'K' sets the minimum bandwidth needed/occupied for the two
recognized cases.  Occupied bandwidth in excess of K=5 (or 400 Hz for
100 WPM) would be unacceptable due to improper keying waveforms or
distortion in the RF stages.
