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)
Implementing an FM broadcast band receiver is really easy with the WBFM Receive Block.
- Python files
- Block definition
