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].

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
