Re: uncertainty principle + searching article

[Eckard Blumschein <Eckard.Blumschein@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Dear Ramin Pichevar, dear Bert Huber,

Thank you Ramin for sending to me the article by P. Loughlin and L. Cohen
entitled 'The Uncertainty Principle: Global, Local, or Both', thank you
Bert for the link to the 'Cochlear Paradox', respectively. Admittedly, the
latter was more inspiring to me. Nonetheless, I wrote a harsh comment:

Please accept my apologies for wrongly claiming that the natural
spectrogram does not obey the uncertainty principle. Things seem to be a
little bit tricky. Be sure that my preference for FCT within IR+ is
correct. Cochlea does not at all throw away phase. It would not benefit
from Heaviside's trick.I see it just preparing joint autocorrelation.

Regards, Eckard

Ask Roy Patterson. Because the natural spectrogram shows frequency chirping
up, I am also interested.
