Thanks for the info. I've trying to come up with a type scheme. Say I create some modulated symbols, then interpolate them with a nyquist filter, then upsample and shift the signal with a mixer. It would be nice to know the relative sample rate and center frequency of the signal, plus mod type.

Thanks. Most of the features listed in the README haven't been implemented yet. I'm struggling with resampling right now, and trying to figure out how to do multistage interpolation/decimation for large rate changes. And I'm definitely lost when it comes to polyphase filtering. That said, basic
