[TangerineSDR] Setting up DE for selected bands and sample rate

[Engelke, Bill]

Words of wisdom to be sure.  It's just that all my other code for working with this data is in C, so I guess I would have to call the Python code from C (?) - Bill

If need be, I can help with that eventually.  However (and I have not seen Skylar's implementation at all), most Python libraries for number crunching are reasonably-thin wrappers around optimized C libraries.
There's a little overhead, but it's not too bad in most cases.  If you needed a bare-metal implmentation, then yes, C might be required, but I urge you to wait for Skylar's implementation and actually try it on your target hardware before starting a C port.

Remember, the first rule of premature optimization is "Don't".
