LimeSDR and PlutoSDR fixes
Fixed segfault when stopping one device in multiple stream configuration. Was due to wrong initialization of shared data copying the other thread address as its own.
SSB demod fix
Refactor the rational decimator filtering. The cutoff was half of what it should be and was like this since quite a long time maybe since the creation of the plugin. In addition relaxed the filtering since the sharp filtering is done by a FFT filter. This can slightly increase performance.
Other changes and fixes
- For all modulators and demodulators: apply initial channel settings at construction and start. This makes sure the proper initialization of channel NCO and interpolator/decimator is always done.
- File Source: fixed missing initialization of the do apply settings flag possibly preventing start.
