I'm currently involved in a software project developing a signal
processing package for neurological signals, and I've been asked to
incorporate a zoom-fft processing option to allow accurate measurement
of hum components in the sampled signal. I have found a few references
to zoom-fft in journals, and the original material appears to be in a 
B & K (Bruel and Kjaer (?sp)) technical review in 1981, written by 
N. Thane - I am having trouble locating this material or any other
material which describes the method in detail.

Does anyone have an algorithm or code (preferably in C, or Fortran or
Pascal if not) for the zoom-fft technique, or even a reference to an
article that does describe the method in detail. Oh, zoom-fft is also
called 'band selectable Fourier analysis'.

Thanks..
