One clarification - On Stacking the digital filters - the bandwidth does not narrow - I misspoke. Naturally being a Hardware Guy I forgot that the digital filters do no load each other, like analog filters can.Actually, considering the quick flow-graph below, using a complex-low-pass as a symmetric bandpass, you can see that doubling-up the same filter produces much more out-of-band attenuation, but also slightly-steeper "skirts".(I should never type before two cups of coffee in the morning - forgive me). ;-)
