Hence the NCO limits are calculated as +/- half the device to host sample rate multiplied by the hardware decimation factor. For example with a 4 MS/s device to host sample rate (5) and a hadrware decimation of 16 (3) you have +/- 32 MHz span around the LO for the NCO.

 As you can see from the Wiki this is becoming a fairly popular SDR hardware platform. It does have interesting features but the library documentation and examples are poor when not misleading. Therefore while this implementation does work it should still be considered experimental.

 The filter limits are calculated as 0.05 and 0.9 times the FIR filter input frequency for the lower and higher limit respectively. The FIR filter input frequency is the baseband sample rate (5) multiplied by the FIR interpolation factor (9)

-For bandwidths greater than 0.2 times the FIR filter input frequency the filter is calculated as a windowed FIR filter with a Blackman-Harris window. This has a high out of band rejection value at the expense of a slightly smoother roll off compared to other filters. The bandwidth value sets the -6 dB point approxomately.
