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 PLL, this one does a simple mono demodulation with deemphasis


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

Implementing an FM broadcast band receiver is really easy with the WBFM Receive Block.
