That's a useful trick to reduce the filtering burden. Having said
that, if you need good spectral purity, the filtering is still
going to be very non-trivial. The original poster is obviously
not an expert in filters and will not be successful trying that
approach, except for very low performance design. Even if
you are a filter expert, components are hard to get.
