Re: two cycles

[Kelly Fitz <kelly_fitz@xxxxxxxxxxx>]

It does not (I think) specifically address this point, but the method 
described in Gardner and Magnasco's paper "Sparse time-frequency 
representations", see

http://www.pnas.org/cgi/reprint/0601707103v1

is offered as a possible explanation for the "remarkable acuity of 
auditory perception". As a signal processing algorithm (that is, 
mathematically), under the right conditions, the reassignment method can 
give quite precise estimates of the frequencies of resolvable components 
given only two fundamental periods.

Perhaps this paper is of interest?

cheers,
Kelly
