Re: Band splitting

Thanks for your help Greg, summing my filter kernels resulted in a delayed
impulse.

Sorry to sound dim but would it be valid to test this by just
summing the two filter kernels?

Yes. If the filters form a perfect reconstruction pair, then the FIR
coefficients (which are also the impulse responses of the filters)
will sum to an impulse. Note that the impulse will be delayed in time
if the FIR filters are causal.
