Greetings:

I'm new to the world of DSP, so please feel free to correct my
terminology and point me towards references as appropriate.

After some research, it seems to me that it would be possible to
convert a signal into a list of power vs. frequency (would this 
be called a conversion to the frequency domain?) with a set of
FIR low pass filters.  Differences between the signal and the
various filters could give band pass power information.

It further seems that these operations could be pipelined such
that a new spectrum could be generated in a fixed amount of
time from sample acquisition.

What current work exists in this field.  Is there some reason
that it is a bad approach (tried and failed?)?  How is real-time
spectral analysis done nowadays.  Thank you.

Regards,

 -Tom
