[Hackrf-dev] HackRF in SDR#

[Marcus Watson]

Caveat: I know more about developing/reverse engineering than I do about 
SDR.

I reverse engineered the SDRSharp.HackRF.dll - in looking for more info 
I then found a year old repository on Github for HackRF and the code 
hasn't changed significantly:

https://github.com/cgommel/sdrsharp/blob/master/HackRF/HackRFDevice.cs

var baseband_filter_bw_hz = 
NativeMethods.hackrf_compute_baseband_filter_bw_round_down_lt((uint)_sampleRate); 

r = NativeMethods.hackrf_set_baseband_filter_bandwidth(_dev, 
baseband_filter_bw_hz);

Does this mean it's using the sample rate to set the baseband filter 
bandwidth?
