Generalized AM demodulation 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].

@param channel_rate: incoming sample rate of the AM baseband
@type sample_rate: integer
@param audio_decim: input to output decimation rate
@type audio_decim: integer
@param audio_pass: audio low pass filter passband frequency
@type audio_pass: float
@param audio_stop: audio low pass filter stop frequency
@type audio_stop: float

AM demodulation block, 10 KHz channel.
This block demodulates an AM channel conformant to 10K0A3E emission standards, such as broadcast band AM transmissions.

@param channel_rate: incoming sample rate of the AM baseband
@type sample_rate: integer
@param audio_decim: input to output decimation rate
@type audio_decim: integer
