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].

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
