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.

Parameters[edit]

Quadrature Rate
Input sample rate of complex baseband input. (float)
Audio Decimation
How much to decimate quad_rate to get to audio. (integer)

Example Flowgraph[edit]

This flowgraph shows the stereo version of the WBFM receiver. The flowgraph file can be found in https://github.com/gnuradio/gnuradio/blob/master/gr-analog/examples/USRP_FM_stereo.grc
