Generalized AM demodulation hierarchical block with audio filtering.
This block demodulates a band-limited, complex down-converted AM channel into the the original baseband signal, applying low pass filtering to the audio output. It produces a float stream in the range [-1.0, +1.0].
Note: The AM Demod block is the same as a Complex to Mag block feeding an Add Const block feeding a Low Pass Filter. See Complex_to_Mag#Example_Flowgraph.
Parameters
(R): Run-time adjustable
- Channel rate
- Incoming sample rate of the AM baseband
- Audio decimation
- Input to output decimation rate
- Audio pass
- Audio low pass filter passband frequency
- Audio stop
- Audio low pass filter stop frequency
Example Flowgraph
This flowgraph shows the use of an AM Demod block to implement an AM broadcast receiver.
