Hi All,
 I am attempting a spectral transformation for FIR filters. My intention is to convert Low Pass
FIR filters to Multiband (Bandstop or Bandpass) FIR filters.

I am aware that such transforms exist for IIR filters and that there are APIs in Matlab like
lp2bs and lp2bp that do this. 

1. Are similar transforms possible for FIR filters ??
2. If YES, what is the method used ??
3. Any Matlab APIs/functions available ??
Cheers,
Madan
