AM Demod

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
