WBFM Receive PLL
Hierarchical block for demodulating a broadcast FM signal.
The input is the downconverted complex baseband signal (gr_complex).
The output is the demodulated audio (float)
Compared to WBFM Receive, this one does a full stereo demodulation.
- Quadrature Rate
- Input sample rate of complex baseband input. (float)
- Audio Decimation
- How much to decimate quad_rate to get to audio. (integer)
