I'm working on a design for a guitar tuner.  The
design I'm thinking of using is a parallel bandpass
filter bank.  The problem I expect to have is
unwanted harmonics generating false readings.

Are there any ideas for some how nulling out
the harmonics and leaving the fundamental?
Remember I want know in advance what the fundamental 
will be (ie out of tune).

Thanx.
