You can do what you wish by using an adaptive filter.  Use
the adaptive filter in a system identification configuratio,
and use white noise as an input.  The adaptive filter will
adjust its coefficients to match that of the bandpass filter.

Also, if you know the transfer function of the desired filter,
the adaptive filter will calculate the coefficients needed
for implementation.
