Name spelling edit

I see von Hann spelled von Hahn in a signal processing textbook, Contemporary Linear Systems by Robert D Strum

Robert D Strum needs to go to Google Books and view images of original Julius Hann title pages to know that Hahn is wrong.

Hanning edit

"the use of the Hann window is called "hanning", e.g., "hanning" a signal is to apply the Hann window to it."

Come off it - there's no such verb as "to hann". 194.75.159.78 (talk) 14:57, 20 April 2010 (UTC)Reply

Well then, how do you explain verbs such as "to Google" (I Googled my teacher) "to Xerox," (You Xeroxed the term paper)...the list goes on and on...

Hanning was a sort of a joke/pun to John Tukey, because they were using the Hamming window (named after R.W. Hamming), which was also known as Hamming it. Given that the Hann window is quite close to the Hamming window in its definition (although with a much better asymptotic rolloff rate of -12 dB/octave rather than -6 dB per octave), this joke was inevitable.
